Wear Resistant AISI ASTM 321 Stainless Steel Plate

AISI/ASTM321 Stainless Steel Plate With Strong Wear Resistance Used In Organic Or Inorganic Acid

1. Description

321 stainless steel is a Ni Cr Ti austenitic stainless steel, its performance is very similar to 304. Because of the addition of titanium, it has better resistance to grain boundary corrosion and high temperature strength, and effectively controls the formation of chromium carbide. Among them, Ti is a stable element, but it is also a hot steel, which is much better than 316L in high temperature. 321 stainless steel has good wear resistance in organic acid and inorganic acid of different concentration and temperature, especially in oxidizing medium, It is used in the lining and transmission pipeline of various heat-resistant equipment, wear-resistant acid container and wear-resistant equipment, and in the key parts of heat exchange equipment of high-temperature boiler.

Performance advantages of 321 stainless steel

1) It has good wear resistance in oxidizing medium;

2) Better grain boundary corrosion resistance and high temperature strength;

3) Excellent high temperature stress fracture performance;

4) Excellent creep resistance at high temperature.

4. Delivery surface states

We offer various surface treatment states. Normally, No1,1D,2D,2B,No.3,No.4,HL,BA and Mirror.

No.1 - A rough, matte surface that is hot rolled to a specified thickness, annealed, and descaled for use without surface gloss

1D - the surface has discontinuous particles, also known as fog surface. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.

2D - slightly glossy silver white. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.

2B - silvery white, better gloss and flatness than 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 mirror surface. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + surface polishing + quenching and tempering rolling.

NO.3 - good glossiness and rough surface. Processing technology: polishing and tempering rolling of 2D products or 2B with 100-120 abrasive materials (JIS R6002).

NO.4 - good glossiness and fine lines on the surface. Processing technology: polishing and tempering rolling of 2D products or 2B with 150-180 abrasive material (JIS R6002).

HL - silver gray with hairline. Processing technology: polishing 2D or 2B products with appropriate abrasive materials to make the surface appear continuous grinding lines.

Mirro - in mirror state. Processing technology: grind and polish 2D or 2B products with appropriate abrasive materials to mirror effect.
