A573Gr.70 chemical composition

A573Gr.70 steel plate introduction
Standard: ASTM A573/573M-19
ASTM A573 grade: 58 grade, 65 grade, 70 grade, three quality grades. A573Gr.70 steel is a carbon-manganese-silicon steel plate for service at atmoSPHEric temperatures where improved notch toughness is important..
A573Gr.70 technical conditions: chemical composition and mechanical properties, impact, flaw detection, Z direction, composition control, performance requirements beyond the standard, etc. can be added when ordering.

A573Gr.70 chemical composition(%):

C	Si	Mn	P	S
≤0.27	0.15-0.4	0.85-1.2	≤0.03	≤0.03

Delivery status: usually delivered by normalizing.
 
Product Usage:
A573Gr.70 steel plate is mainly used to improve notch toughness at room temperature. Petroleum and chemical equipment towers, CO2 absorption towers, medium pressure flash towers, coolers, reabsorption towers, compressor casings, low temperature 130 storage tanks 0762 manufacturing 1023, etc. gradually replaced imported low temperature container steel plates. Petrochemical equipment, power stations, boilers and other industries are used to make equipment and components such as reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, nuclear reactor pressure shells, boiler drums, high-pressure water pipes of hydropower stations, and turbine volutes.
