ASTM A204 Grade B welded steel, ASTM A204grA/B/C steel grade

ASTM A204 Grade B welded steel, ASTM A204grA/B/C steel grade

Posted:2014-11-30 13:19:30
ASTM A204-B steel is a kind of material for boiler and pressure vessel steel. So, ASTM A204-B steel is used above all for
manufacturing boilers, pressure vessels and pipes transporting hot liquids.
ASTM A204-B welded steel tubes for pressure purposes. Electric welded non-alloy and alloy steel tubes with specified elevated temperature properties.
About ASTM A204-B steel, we can offer A204-B steel plate specifications according to your requirements:
Thickness: 6MM to 150MM,
Width: 1500mm to 4050mm,
Length: 3000mm to 15000mm
Molybdenum alloy boiler steel plate A204 Grade B contains a higher Carbon than boiler steel plate A204 Grade A,so pressure vessel steel plate A204 Grade B ownd a higher yield strength and tensile strength at 485-620 Mpa.The steel for rolling boiler steel plate SA204 Grade B shall be full killed.Besides ultrasonic examination is neccessary,the following test shall be chosed by the end users when ordered:S1 Vacuum treatment,S3 Simulated post weld heat treatment of mechanical test coupons, S5 Charpy V-notch impact test, S7. High temperature tension test.
