Grade 304H Stainless Steel Coils/Strips
What Is Stainless Steel Strips Surface Finish?
Stainless steel has become a widely used metal material for its excellent corrosion resistance, good mechanical properties and processing properties.
Through different processing methods of cold rolling and surface reprocessing after cold rolling, the surface finish of stainless steel can have different types.
The surface processing of stainless steel strips have NO.1, 2B, No. 4, HL, No. 6, No. 8, BA, TR hard, Rerolled bright 2H, polishing bright and other surface finishes, etc.
304(1.4301)/304L(1.4307)/304H(1.4948) STAINLESS STEEL
Stainless Steel Grade 304H includes a high carbon content making the steel more suitable for utilization in applications where high temperatures are available. The benefit of this grade is that it is an austenitic chromium-nickel steel alloy as well as the greater carbon content distribute to increased tensile and yield strength. The material is recommended for utilizing in ASME pressure vessels in working service above 525° C because of the grade's heat resistant properties.
