JIS SUS301 stainless steel spring steel strip 2b finished Cold rolled
Product Description
301—Good ductility, used for molded products. It can also be hardened by machine. Good weldability. Abrasion resistance and fatigue strength are better than 304 stainless steel.
302—Corrosion resistance is the same as 304, because the carbon content is relatively high and the strength is better.
303—Through the addition of a small amount of sulfur and phosphorus, it can be cut.
304— 18/8 stainless steel. The GB grade is 06Cr19Ni10.
309—has better temperature resistance than 304.
316—After 304, the second most widely used steel type is mainly used in the food industry and surgical equipment. The addition of molybdenum makes it a special structure resistant to corrosion. Because it has better resistance to chloride corrosion than 304, it is also used as "marine steel". SS316 is usually used in nuclear fuel recovery equipment. 18/10 grade stainless steel usually also meets this application level.
321—The performance is similar to 304 except that the addition of titanium reduces the risk of corrosion of the material weld.

1D—The surface has discontinuous particles, which is also called matte. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
2D—Slightly shiny silver-white. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
2B—Silver white and better gloss and flatness than 2D surface. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + quenching and tempering rolling.
BA—The surface gloss is excellent and has a high reflectivity, just like the mirror surface. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + surface polishing + quenched and tempered rolling.
No.3—has better gloss and rough surface. Processing technology: Polishing and tempering rolling of 2D products or 2B with 100 ~ 120 abrasive materials.
No.4—has better gloss and fine lines on the surface. Processing technology: Polishing and tempering rolling of 2D products or 2B with 150 ~ 180 abrasive materials.
HL—Silver gray with hair streaks. Processing technology: Polish the 2D product or 2B product with a suitable size of abrasive material to make the surface appear continuous grain.
MIRROR—is in a mirror state. Processing technology: 2D or 2B products are ground and polished to a mirror effect with a suitable abrasive material.
