Uses and models of 304 stainless steel plate

304 stainless steel plate is an austenitic stainless steel containing 16% to % chromium and up to 35% nickel. It is the most common and widely used stainless steel variety with good corrosion resistance, heat resistance, low temperature strength and mechanical properties; good hot processing properties such as stamping and bending, and no heat treatment hardening phenomenon (use temperature -196℃～800℃).

The surface of 304 stainless steel plate is beautiful and has diverse possibilities for use. Its chemical composition is shown in the following table:

The physical properties of 304 stainless steel plate are shown in the following table

Due to its excellent performance, 304 stainless steel plate is widely used in the following fields:

(1) Food field: suitable for food processing, storage and transportation, such as kitchen utensils, production equipment, tableware, cabinets, etc.

(2) Chemical field: suitable for chemical storage, transportation and production equipment, such as plate heat exchangers, bellows, etc.

(3) Construction field: beautiful, high strength, good corrosion resistance, can be used for home decoration, building materials, exterior materials, etc.

(4) Medical field: used to produce medical equipment, surgical instruments, etc., with good hygiene and safety.

(5) Automobile manufacturing field: high strength and good corrosion resistance, so it can be used in automobile parts, such as exhaust pipes, mufflers, body trims, etc.

(6) Other fields: such as fiber industry, ship parts, nuclear energy, etc.

304 stainless steel plate can be divided into the following types according to its surface state and thickness:

(1) 304/2B: 2B means a smooth surface formed by annealing and calendering after cold rolling, with a general thickness of 0.3-3mm, widely used in industrial and civil fields.

(2) 304/BA: BA means a bright surface formed by bright annealing after cold rolling, with a general thickness of 0.3-2mm, mainly used in home appliances and kitchen utensils, etc.

(3) 304/NO.1: NO.1 means a rough surface formed by annealing and pickling after hot rolling, with a general thickness of 3-50mm, mainly used in chemical industry, shipbuilding, etc.

(4)304/NO.4: NO.4 indicates a surface with a certain gloss after cold rolling and fine rolling, with a general thickness of 0.4-3mm, mainly used for decoration, elevators, etc.

(4)304/HL: HL indicates a surface with fine stripes after cold rolling and fine rolling and polishing, with a general thickness of 0.4-3mm, mainly used for construction, elevators, etc.

(5)304/8K: 8K indicates a surface with a mirror gloss after cold rolling and super fine rolling and polishing, with a general thickness of 0.3-2mm, mainly used for high-end decoration, home appliances, etc.
