China 20 Gauge Galvanized Sheet Metal - A283 A285 Hot rolled steel plate Cold rolled steel plate A36 – Ruiyi

A283 Grade C steel is machinable with common operations such as cutting, grinding and welding.
Application:
A283 Gr C steel is mainly used to build factories, high voltage power transmission tower, Bridges, vehicles, boiler furnace, containers, ships, etc., also a lot less used as performance requirements for mechanical parts.

Dimensional Characteristics of Grade A Steels: The applicable thickness for this Grade A material as defined in the ASTM A283 starts from 6 mm to 50 mm. The width is normally from 600 mm to 2000 mm.

The Chemical Composition of Grade A Steels: ASTM A283 defines the chemical composition of Grade A steels as under:

Maximum percentage of Carbon (C) is 0.14

Maximum percentage of Silicon (Si) is 0.4

Maximum percentage of Manganese (Mn) is 0.9

Maximum percentage of Phosphorous (P) is 0.035

Maximum percentage of Sulphur (S) is 0.040

Minimum percentage of Copper (Cu) is 0.20

Remaining is iron (Fe) percentage and with few negligible impurities

ASTM A285 is a type of ordinary carbon steel intended for fusion-welded pressure vessel equipments as boiler, storage tank, heat exchangers, etc. With 3 steel grades (Grade A, Grade B, Grade C) covering tensile strength range from 310-515Mpa,usually ASTM A285 steel plate is delivered as-rolled condition. made by killed, semi-killed, capped or rimmed steel practices according to the end users’ requirement.
ASTM A285 steel could be manufactured into many steel product forms, steel plates, steel coil, steel pipe, it has good weld-ability for fusion weld need for pressure vessel equipment, its max thickness is limited to 50mm in order to insure its mechanical property

ASTM A283 is designed as a type of carbon steel plate for general structural purpose, this steel has low and intermediate tensile strength, it has 2 steel grades(Grade C, Grade D) . For steel plate made from coils or with no heat treatment, additional test is required for its stress relieving, usually after steel coil is decoiled, inspection, conditining, heat treatment are required before delivering. ASTM A283 is only used for structural purpose, while ASME SA283/SA283M steel plate could also be used in boiler and pressure vessel manufacture. Availlable ASTM A283 steel product form covers steel plate, steel coil, steel pipe, and structural steel products as steel sections, beams, if you need to buy ASTM A283 steel plate, contact us now.
