SA387 GR22 CL2 steel plate has the properties of preventing hydrogen embrittlement, hydrogen corrosion, hydrogen peeling, and sulfide corrosion, as well as good low temper embrittlement. It is widely used in the manufacture of fertilizer, petrochemical and thermal power plant equipment. BBNSTEEL has leading production technology, and there are many S420ML material specification products in stock. If you need to fix it, it can be 8mm-120mm-650mm thick and wide to 3900mm.

When using S420ML material specification, 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.

In addition to quality assurance, service is also important for the competition of steel suppliers. All the after-sales service personnel of the company have received professional training and assessment.
