Comparial is the online platform enabling you to quickly search for materials. With Comparial you can directly compare the most important properties of a wide range of steel grades.


You can search easily and intuitively according to:

  • Steel grades (e.g. 42CrMo4, S355J2, ST52)
  • Properties (e.g. density, corrosion, tensile strength, yield point or modulus of elasticity)
  • Material numbers (e.g. 1.4404, 1.2379, 1.5415) or
  • Standards (EN 10088-3, DIN EN 10025).


Comparial presents the material data you have chosen in an easy-to-view PDF fact sheet which can be printed out or downloaded.


Compare more than 11,000 steel grades

Steel grades are specified in DIN EN 10027-1 and DIN EN 10027-2. In addition to the steel designation system according to number and the classification of steel grades according to chemical composition, each steel grade has its own symbol. With its one-of-a-kind, practical overview of steel grades, Comparial provides you with all steel designations, including complete information on material properties and composition.

High-grade steel: Table of material properties

This database contains all important information on high-grade steel. Comparial provides you with all material data on high-grade steel: properties, tensile strength, yield point, coefficient of thermal expansion and much more. Use the practical material database to compare high-grade steel alloys and find exact material designations in a clearly arranged table, including material numbers for high-grade steels.


Metals: Properties and material numbers in one database

Comparial provides you with a complete materials table on metal. Find all metal designations and the most current standards in a digital book of tables. Get a detailed overview of metal properties such as temper, Vickers hardness, strength, tensile strength and everything else you need to know about metal.


Structural steel - Data sheet of all designations and properties

Structural steel makes up more than half of worldwide steel production. In Comparial, you can find all grades of structural steels in a digital data sheet. Easily compare different grades of structural steels, such as st37-2 (S235JR) and st52-3 (S355JO). Quickly access all properties of a particular material according to DIN EN 10025 (structural steel) such as specific weight, yield point, tensile strength and its exact composition (carbon content, chemical composition). Use the digital database on structural steel, find the right material and move your project forward.


Spring steel – Data sheet of properties and composition

Specifications on spring steel are laid out in DIN EN 10089 among other standards. It is known for its distinct strength. Comparial contains a digital materials database where you will find all steel grades that fall under the designation “spring steel”. Here you have access to all important information on spring steel: properties such as yield point, tensile strength, density, and weldability. Use the practical materials data sheet to compare different spring steel standards and spring steel tempers.


Free-machining steel – All properties and composition

Free-machining steel is by definition an alloyed steel and has good machinability. This material’s designation as free-machining steel is a result of its optimization for drilling and turning in automatic manufacturing equipment. All properties of free-machining steel such as tensile strength, density, temper and composition can be found on the digital materials data sheet from Comparial – precisely, quickly and with a practical comparison function.

Steel properties with a click of the mouse


When it comes to materials, you need to have all your facts straight. Comparial gives you the largest digital materials database at your fingertips. With just a few clicks you can get properties of steel and make comparisons quickly. Using material numbers, DIN Standards and all standards from other international standards-setters (e.g. ASTM, JIS), or common names of steel grades, you can find the chemical composition and the specific mechanical properties of that steel. Comparial provides you with the material properties of more than 11,000 steel grades.


Steel grade densities

It is generally said that the density of steel is 7,85–7,87 g/cm3 (7850–7870 kg/m3). But which steel grade has exactly which density? Comparial gives you the specific density of steels in a handy table – digitally, simply and with a practical comparison function. Find out the raw densities of all steel grades, including structural steel, high-grade steel, free-machining steel or spring steel.


E-modulus steel – Exact figures and comparison option

The material characteristic “modulus of elasticity” outlines the relationship between the stress and strain in materials such as steel. It is also called the e-modulus. Steel has an e-modulus of between 200.000 N/mm² (e.g. for steel grade S210) and 220.000 N/mm² (e.g. for steel grade S220). You can find the exact e-modulus for individual types of steel in Comparial’s practical digital materials database. Easily compare steel grades and their e-moduli (e.g. for spring steel) and find the right material for your project.


Coefficient of thermal expansion for steel

The coefficient of thermal expansion describes the behaviour of a material such as steel with regard to its dimensions when undergoing changes of temperature. It is also referred to as the thermal expansion coefficient and varies depending on the material. For steel, the standard value of 11,7 is typically given for the thermal expansion coefficient, but the value can vary greatly according to steel grade. The thermal expansion coefficient of high-grade steel, for example, is different than that of other high-alloy steels. With Comparial, you have access to exact data on the thermal expansion coefficient of steel in a handy digital table.

Standardization of steel – EN, DIN and steel names (European material standardization)

According to European material standardization, every steel grade receives its own material number which is guaranteed by the manufacturer to have certain properties resulting from different thermal treatment and composition. In Germany, the European Standard (EN) is adopted into the body of German standards as a DIN EN standard. Structural steel grades begin with the prefix “S” according to EN 10025. Steel has additional letters in its material number based on material properties, such as K for cold-worked or A for tempered. In Comparial, you will find all materials standardized in Europe in a clearly-structured digital materials database.

Semi-finished steel products – All properties in one materials database

All steel products have specific technological properties that are of utmost importance to you. Before further processing (e.g. before machining) of the steel product or workpiece, it is necessary to be aware of the composition and properties of the steel. In Comparial, you will find all details on steel products- such as flat rolled steel, pipes and profiles - in a practical online table.


Steel pipe standards and comparison

Steel pipes are standardized according to DIN EN and differ not only in their wall thickness and outer diameter, but also in their material composition and associated weight, ductility and heat resistance. Find all relevant steel pipe standards on different types of pipes with Comparial – it’s fast, simple and has a comparison function.


Steel profiles – Properties, material numbers and standards

Sectioned steel, also hot-rolled steel, is not only used for steel beams. You need the C-steel material number for your project? Comparial provides you with a unique digital table with dimensions, material properties and material numbers of individual steel profiles. You can find the right sectioned steel for your project in mere seconds using the comparison function.


Flat steel – Properties of long products

The hot rolled flat steel bars specified in DIN EN 10058 are important products for the steel processing industry. In general, these steel bars are hot rolled, yet there are flat steel products that are cold drawn and made of many different grades of steel. Find all the information you need on flat steel, including properties, in the flat steel table from Comparial - ranging from free-machining steel to spring steel.


Steel sheet standard and corresponding material designations

Whether its steel sheet, electrical sheet or flat sheet, they are covered by sheet standards and have corresponding material designations. Thin sheets, for example, are designated as material DC01. There are both hot rolled and cold rolled sheets. The various steel products have clear differences in their properties, e.g. density or chemical composition. With one click of the mouse, you will find all important details on steel sheet in the practical and comprehensive Comparial materials database.
