Austenitic stainless steel has good plasticity and low strength, but its corrosion resistance is the best among the stainless steels. Q355GNH Z35 plate, Austenitic stainless steel is suitable for the occasions where the mechanical properties are not required to be very high, such as chemical plants, chemical fertilizer plants, sulfuric acid and hydrochloric acid manufacturers, etc. Of course, austenitic stainless steel can also be used in submarine and other military industries.

Titanium microalloying is an element of Q355GNH Z35 plate strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in Q355GNH Z35 plate tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.

JIS g3101:2004 ss540 structural steel angle contains 0.30% carbon and 1.60% manganese, which greatly improves the strength of steel. Compared with Q355GNH Z35 plate SS400 and ss490, ss540 has higher strength with yield strength of 400MPa and tensile strength of 540Mpa. High strength makes it popular in applications that require strength but weight is a problem.
