EN10028-6 P500QH steel

This material belongs to EN10028-6,and it have quenched and tempered heat treatment,

Our P500QH sheets widely used in the manufacture of all kinds of boiler and important attachments, because the boiler plate in medium temperature (below 350 ° C) work under the high pressure condition, except under high pressure and impact, fatigue load and water and gas corrosion, and the requirements to ensure certain strength, but also has the good welding, cold bending performance.

Katalor P500QH steel products widely used in petroleum, chemical industry, power stations, boilers and other industries, for the production of reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear reactor pressure shell, boiler drum, liquefied oil and gas cylinders, hydropower station high pressure water pipe, turbine volute and other equipment and components.

For the pressure purpose steel such as P500QH,some people may do the PWHT,so we kindly advising excessive post weld heat-treatment (PWHT) conditions can decrease the mechanical properties.It is therefore recommended that the purchaser seeks, at the time of enquiry and order, the advise of the manufacturer and considers, where appropriate, the verification of the mechanical properties on simulated post weld heat treated samples.

Below is the chemical composition and mechanical property of the P500QH steel.

EN10028-6 P500QHH Chemical Composition

According to EN10028-6 standard,P500QH elements not listed in this table shall not be intentionally added to the steel without the agreement except for finishing the cast. All appropriate measures shall be taken to prevent the addition from scrap and other materials used in steelmaking of these elements which may adversely affect the mechanical properties and usability.

EN10028-6 P500QHH Mechanical Property

As you can see,the P500QH steel plates,when t≤50,Yield strength(Mpa) is 500Mpa,  Tensile strength(Mpa) is 590-770 Elongation(%)Min:17%.
