What is SA283 Gr.C steel

SA283 Gr.C, carbon structural steel belonging to American standard

Implementing ASTM standards, the steel plates are divided into four grades: SA283 Gr.A, SA283 Gr.B, SA283 Gr.C, SA283 Gr.D.

ASTM SA283 steel has good mechanical properties and is generally used for riveting, bolted links and welded structural parts for bridges and buildings.

SA283GrC steel plate technical standard: ASTM A283/A283M-03; heat treatment delivery status: hot rolling, TMCP, normalizing; ultrasonic inspection standard GB/T 2970-2004.

SA283 Gr.C steel plate application:
SA283 Gr.C is mainly used in petroleum and petrochemical industry, chemical equipment manufacturing enterprises, power station construction, boiler and pressure vessel manufacturing, etc.

SA283 Gr.C Chemical Composition:
C:≤0.24
Si: (steel plate≤40) ≤0.40 (steel plate＞40) 0.15-0.40
Mn: ≤0.90
S:≤0.040
P: ≤0.035
Cu:≤0.20

Mechanical properties of SA283 Gr.C:
