Equivalent Material of 321 Stainless Steel  Sheet

Standard Specification Of 304L Plate

321L stainless steel composition content.

321 Stainless steel sheet manufacturer

Stainless Steel 321 Sheets can be welded using most of the resistance and fusion methods. Stainless Steel 321 Plates also possesses good low temperature toughness and is non-magnetic in the annealed condition. In addition to its heat resistance properties, Stainless Steel 321 Coils also enjoys better resistance against creep and stress rupture corrosions. Stainless Steel 321H Sheets is used in Oil Refineries, Fluid catalytic cracking units, Hanger rods, and more. Like most other austenitic alloys, Stainless Steel 321H Plates work hardens and may require annealing after severe forming. Niobium in Stainless Steel 321H Coils has been added to suppress grain boundary Chromium Carbide precipitation.

Stainless steel is a kind of material with brightness close to mirror surface, tough and cold touch. It is a relatively avant-garde decorative material with excellent corrosion resistance, formability, compatibility and toughness. It is used in heavy industry and light industry, Daily necessities industry and architectural decoration industries.

Feathurs:

 2. Stainless steel can be customized for different surfaces, and different surfaces have different applications. For example, 8k mirrors are generally used for decoration.

321 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.
