Boiler steel plate A302GrD, ASTM A302 Grade D pressure vessel steel plate

Posted:2014-11-30 14:25:24

Boiler steel plate A302 Grade D is a kind of alloy steel with Manganese,Molybdenum and nickel.A302 Grade D contains a higher Nickel element in rolling than Boiler steel plate A302 Grade C.Pressure vessel steel plate owned the same value range in mechanical property as A302 Grade B and A302 Grade C,yield strength above 345 Mpa,and tensile strength within 550-690 Mpa. Katalor would like to offer MTC under format EN 10204 3.1 or EN 10204 3.2 with third party inspections.

ASTM A302 Grade D steel chief application:
ASTM A302 Grade D pressure vessel steel plate is widely used in petroleum, chemical industry, power station, boiler, etc, used to make the reactor, heat exchanger, separator, spherical tank, liquefied gas, nuclear reactor pressure vessel, boiler steam drum steam, liquefied petroleum, hydropower station, high pressure pipe.

ASTM A302 Grade D steel Mechanical Properties:

Grade	Tensile strength kis [MPa]	Yield strength min, kis [MPa]	Elongation in 8 in. [200 mm], min, %	Elongation in 2 in. [50 mm], min, %
A302 Grade D	80-100[550-690]	50 [345]	17	20
