Stainless steel coil, sheet and plate

Stainless Steel
It’s the material which can withstand all kinds of acid corrosion of oxalic acid, sulfuric acid - ferric sulfate, nitric acid, nitric acid - hydrofluoric acid, sulfuric acid - copper sulphate, phosphoric acid, formic acid, acetic acid. It is widely used in chemical, food, pharmaceutical, paper, oil, atomic energy and other industries, as well as architecture, kitchen utensils, cutlery, vehicles, household appliances and all kinds of parts.

In order to ensure the mechanical properties of yield strength, tensile strength, elongation and hardness of various types of stainless steel plate, it must be after annealing, solution treatment, aging treatment and other heat treatments before delivery.

The corrosion resistance of stainless steel depends on the alloy composition (chromium, nickel, titanium, silicon, aluminum, manganese, etc.) and internal organizational structure, chromium plays a major role. Chromium has a high chemical stability, can form a passive film on the surface of steel, the passive film can isolate the metal from the outside world and protect the steel plate from oxidation, and to increase the corrosion resistance of steel plate. After the destruction of the passive film, corrosion resistance will be decreased.

polished with 150~180 mesh abrasive. Compared to No.3, this product has a finer abrasion condition. Its surface is an attractive silvery-white

bathtubs, building exterior and interior, and food industry.

No.2B
No. 2B is the type that had skin-pass (temper-rolling) performed on No.2D. It has better gloss and surface flatness compared to No.2D. It is the standard surface class with improved mechanical properties

It is applicable for almost all uses.

No.2D
No. 2D is a non-glossy cold-rolled product that has undergone annealing and pickling treatment after cold rolling

Used in petrochemical plants, automobile parts, building materials, and pipes.

BA
BA is bright and highly reflective surface produced by bright annealing after cold rolling.

used in home appliances, small-sized mirrors, kitchenware, building materials and others that require reflective properties.

HL
HL is a type of surface with continuous striped pattern acquired by polishing the surface with No.4 abrasive.

It is widely used for building exterior and interior, sashes and doors.

Dull
Dull surface is matte finish produced by reducing gloss from No.2B and creating roughness on the surface.

building exterior and interior, roofing and elevators that require reduced light reflection.

NO.7
polished with 600 mesh abrasive.

Art, decoration

NO.8
Polished with mirror polishing wheel

Reflective mirror, decoration

NO.240
Performed on NO.2D and NO.2B material, polished with 240 mesh abrasive

kitchen installations

NO.320
Performed on NO.2D and NO.2B material, polished with 320 mesh abrasive

kitchen installations
