hardox 400 abrasion resistant need painting or not

A387Gr91 plate is a chromium-molybdenum alloy steel. It has the functions of hydrogen embrittlement, hydrogen corrosion, hydrogen stripping, and sulfide corrosion in a hydrogen environment at medium temperature (350-480 ℃). It also has good low tempering brittleness. HARDOX 400 abrasion resistant, A387Gr91 alloy steel is widely used in the manufacture of chemical fertilizers, petrochemicals, and thermal power plant equipment, such as synthetic ammonia reactors, coal gasifiers, shift furnaces, and hydrogenation reactors.

When using HARDOX 400 abrasion resistant, low-alloy high-strength steel, it is desirable to take advantage of its high strength and use a thinner section, not only for saving weight but also for the economy as much as possible. However, the corrosion factor must be fully considered. The thinner the steel section, the more attention should be paid to corrosion protection. Some low-alloy high-strength steels have good atmospheric corrosion resistance, which can not only improve the effect of anti-corrosion coatings, but in some cases, take appropriate precautions and can even be used without being coated in the atmosphere.

we also provide the HARDOX 400 abrasion resistant welding service for customers, and our welding method, hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding and so on. And we have lots of successful HARDOX 400 abrasion resistant welding project, such as longitudinal submerged arc welding pipe, welding cross colume, prestressed truss and welding box colume.

The high strength HARDOX 400 abrasion resistant low alloy steel, which is shorten as HSLA steel, is one of our main products. We have professional team to serve you. For any demands or questions about HSLA steel, for example, ASTM A572 grade 50 chemical composition, difference between S355JR and S355J2, mechanical properties of HARDOX 400 abrasion resistant ST52 steel, Q345B tensile strength, Q345D steel ASTM equivalent, HSLA steel price etc. , please do not hesitate to contact us and consult.

We guarantee to provide all technical data required by users within one hour to provide reasonable quotation; to provide HARDOX 400 abrasion resistant reasonable quotation for products consulted by users within one hour; to provide investigation reception: we guarantee to receive the investigation of users at any time and provide various convenient conditions for users.
