SS 317 is an improved version of other stainless steel alloys with molybdenum alloy buildup. This is done to increase strength and improve pitting resistance. SS 317 alloy plate has good toughness and temperature strength. Stainless steel 317 on the other hand, is a lower carbon version of the 317 grade alloy with the same corrosion resistance and strength. They all have high breaking stress and higher tensile strength. Cold working is performed on stainless steel 317/317L, which can be annealed in the temperature range of 1850 F and 2050 F.
We supply a comprehensive range of stainless steel perforated sheets in a choice of hole sizes, pitches, patterns and sheet thicknesses. Suitable for a range of applications perforated type 317 stainless steel sheets possess many useful qualities including thermal capabilities and corrosion resistance, making perforated stainless steel ideal for many internal and external applications. Perforated stainless steel 317 metal sheets are widely used in the automotive industry, pharmaceutical, medical and petro-chemical sectors. Some applications include filtration, sterilisation, flooring, and architectural infill panels.

Characteristic machining technology
1D -- The surface has discontinuous granular shape, also known as fog surface.
Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
2D - A slightly silvery white colour.
Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
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.
Processing technology: 2D products or 2B products with appropriate granularity of the grinding material grinding and polishing to the mirror effect.
