309S Stainless steel strip manufacturer

309S is a free cutting stainless steel with sulfur, used in applications where free cutting and high surface smoothness are the main requirements.
 

309S Stainless steel strip Price in China ,Manufacturer of 309S Stainless Steel strip

309S corresponding to the Chinese brand is 0Cr23Ni13, the American standard S30908 (AISI, ASTM) characteristics and use: corrosion resistance, heat resistance are better than 0Cr19Ni9.
The 309S is a variant of the lower carbon 309 stainless steel for use where soldering is required.
The lower carbon content minimizes the precipitation of carbides in the heat affected zone near the weld, which may lead to intergranular corrosion (welding erosion) of stainless steel in some environments.

It can withstand repeated heating below 980 ℃, and has high high temperature strength, oxidation resistance and carburizing resistance.
Application: Furnace material.
Widely used in boilers, energy (nuclear power, thermal power, fuel cell), industrial furnaces, incinerators, heating furnaces, chemical, petrochemical and other important fields.

309S 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.
