420 Stainless steel strip manufacturer
420 stainless steel is a kind of martensiform stainless steel, with certain wear resistance and corrosion resistance, higher hardness characteristics, suitable for all kinds of precision machinery, bearings, electrical, equipment, instruments, meters, transportation vehicles, household appliances, etc.
Mainly used in the manufacture of atmospheric, water vapor, water and oxidizing acid corrosion parts.
420 Stainless steel strip Price in China ,Manufacturer of 420 Stainless Steel strip
420 stainless steel is 420 "tool grade" martensitic steel, similar to Brinell high chromium steel, the earliest stainless steel.
420 has a certain wear resistance and corrosion resistance, high hardness, its price is a lower class of stainless steel ball, suitable for the general requirements of stainless steel working environment.
420 stainless steel is suitable for all kinds of precision machinery, bearings, electrical, equipment, instruments, meters, transportation vehicles, household appliances, etc.
This is the most cost effective grade of steel. So the 420 Stainless Steel strip Price is lower compared to other grades of stainless steels and all metallic products in general. There are different versions of the material with low carbon and high carbon content. The low carbon version, 420 strips are very good for welding applications as they have less carbide precipitation and less localized corrosion.

420 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.
