However, as a lot as methodology and rules have been essential in preparing this handbook, there have been many situations the place they’d not cover every variable and circumstance. Therefore, troublesome comparison decisions as those described previously had to be made. There had been literally hundreds, if no more than a thousand, such choices made in this handbook. In these instances, the closest match comparability decisions were made on the discretion of the editor. There are many alternatives to make technical errors which will lead to inappropriate metal comparisons.

  • For instance, a carbon metal containing 0.45 % carbon is designated 1045 on this system.
  • The SAE system makes use of a basic 4-digit system to designate the chemical composition of carbon and alloy steels.
  • Throughout the system, the final two digits give the carbon content material in hundredths of a %.
  • Resulfurized carbon steels are designated inside the sequence 11XX, resulfurized and rephosphorized carbon steels 12XX and steels having manganese contents between 0.9 and 1.5 %, however no other alloying elements are designated 15XX.

four.three For a new UNS number to be assigned, the composition must be significantly completely different from that of any metal or alloy which has already been assigned a UNS number. four.three.1 In the case of metals or alloys which might be usually identified or specified by chemical composition, the chemical composition limits must be reported. four.3.2 In the case of metals or alloys which are normally recognized or specified by mechanical properties, such properties and limits thereof should be reported. Only those chemical elements and limits, if any, that are important in defining such supplies need be reported. 4.4 Requests for brand spanking new numbers shall be submitted on “Application for UNS Number Assignment’’ varieties (see Fig. 1 and Fig. 2).

At best, one may be able to group comparable steel standards collectively primarily based on some outlined algorithm, which has been carried out in this handbook. For instance, ASTM A 516/A 516M Grade 70 is similar to JIS G 3118 image SGV 480 and to EN steel name P295GH, primarily based on chemical compositions and mechanical properties. Yet they aren’t equal since there are differences in their chemical compositions and mechanical properties. Comparing steel standards is not an actual science and can’t be made right into a mathematical equation where two sides of an equation are equal to at least one another, since there will always be variations between requirements. These variations may be significant to at least one person, however not important to a different person. Therefore, this handbook makes use of the time period comparative to denote related requirements that have been in contrast to one another. Comparative is a relative word that’s inevitably dependent upon the top person’s requirements, who’s finally liable for choosing the appropriate steel for a selected software.

Relative grade of EN10025-6:


1. EN 10025-6 steel grade specification is a high yield strength structural steels in the quenched and tempered condition steel plate grade in S460Q, S460QL, S460QL1, S550Q, S550QL, S550QL1, S500Q, S500QL, S500QL1, S960Q, S960QL, S620Q, S620QL, S620QL1, S690Q, S690QL, S690QL1, S890Q, S890QL1 and S890QL steel plate grade.

S550Q steel plate is a hydroelectric steel plate, which is a low-alloy high-strength steel plate. It is a German standard steel plate. It has the characteristics of high yield and more strengthening alloy elements.
Mechnical property for EN 10025-6 S550Q High strength steel:

2. Delivery status: delivery in quenched and tempered quenched and tempered state.
It is also possible to add flaw detection standard requirements, flaw detection level requirements, Z-direction performance requirements, requirements for adding special alloy elements, etc., but it needs to be communicated between the supplier and the buyer and indicated in the contract.

6. What is EN 10025-6 QT S550Q STEEL?
EN 10025-6 QT S550Q STEE also named as S550Q high strength low alloy steel plate under steel stand EN 10025-6 which is for hot rolled structural steels with high yield strength and tensile strength in quenched and tempered delivery condition.Quenching operation which consists of cooling a ferrous steel plate more rapidly than in still air.

Tempering heat treatment applied to a ferrous steel plate generally after quench hardening or other heat treatment to bring the properties to the required level.S550Q shall be done low temperature impacting test under minus 20 centigrade.


bluing, n—subjecting the dimensions-free floor of a metal object to the action of air, steam, or other agents at a suitable temperature, thereby forming a thin blue movie of oxide and bettering the object’s appearance and corrosion resistance. DISCUSSION—This time period is ordinarily utilized to sheet, strip, or finished components. It is used additionally to denote the heating of springs after fabrication to be able to enhance their properties. A 941 – 03 are held stationary or oscillated in the course of the thermal processing cycle.
In this way, the user should first think about the information within the A table, then see how nicely the data in the B desk match the steels that are being in contrast. For instance, ASTM A 958 Grade SC 4330 has one chemical composition, but has 13 completely different strength classes based on warmth therapy . So simply because two metal grades have comparative chemical compositions doesn’t imply that they are comparable in mechanical properties, and vice versa. Using data found on this handbook is only one step in finding appropriate comparable steel for the supposed utility. With this basic methodology in place, the following is an inventory of the comparison rules that were established to provide this handbook. The minimal content of 0.015% applies to soluble aluminium,this worth is thought to be attained if the total aluminium content material material is no less than 0.018%; in case of dispute the soluble aluminium content shall be decided New opportunities for patrons!
