Stainless Steel 310S Perforated Sheetis quite hard as well as wear resistant and tough. They are also inert to the local overheating and can be engineered to specific service needs. Also, these perforated sheets have stable dimensions during tempering as well as hardening. It contains carbide formers like the vanadium, molybdenum, tungsten as well as chromium in various combinations. Also, nickel or cobalt is added so as to improve the temperature performance of the product. These sheets are made into flat products and the long product which have the coating on a surface like a hot rolled or cold formed.
310S perforated stainless steel sheet can be used for many technical purposes such as filters, strainers and sieves in food processing, brewing and acoustic diffusers as well as interior design and architectural features.

Characteristic machining technology
2B -- Silver white with better gloss and flatness than a 2D surface.
Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + quenching and tempering rolling.
Ba - Excellent surface gloss, high reflectivity, like a mirror surface.
Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + surface polishing + quenching and tempering rolling.
No.3 -- Good gloss, coarse grain surface.
Processing technology: polishing and tempering rolling for 2D or 2B with 100~120 abrasive materials (JIS R6002).
No.4 -- Good gloss, fine lines on the surface.
Processing process: polishing and tempering rolling for 2D or 2B with 150~180 abrasive materials (JIS R6002).
HL -- Silver grey with hair streaks.
Processing technology: 2D products or 2B products with appropriate granularity of abrasive materials for polishing the surface is a continuous abrasive grain.
MIRRO -- Specular.
