Introduction of SA213T12 alloy steel pipe and tube
Source:Xinsteel   Date:2020-04-08
SA-213M T12 / SA-335 P12 belongs to 1Cr-1 / 2Mo pearlite low alloy heat-strength steel. The material has good process performance and welding performance, and has high thermal strength and oxidation resistance below 550 ℃.
This steel is relatively close to 15CrMoG in China's GB5310, and is widely used in heating surface piping such as boiler superheaters and reheaters such as 300MW and 600MW, and reheaters, headers, and main steam pipes.
1. Material grade: SA213-T12
Standard: SA-213 / SA-213M seamless ferritic and austenitic alloy steel tubes for boilers, superheaters and heat exchangers
Country and Region: USA
Main chemical composition (%)
C 0.1500
Mn 0.3000-0.6100
Cr 0.8000-1.2500
Mo 0.4400-0.6500
2. SA213 is the standard number of ASME, which means "seamless ferritic and austenitic alloy steel tubes for boilers, superheaters and heat exchangers"
T12 is a grade number, referring to Cr1Mo0.5 heat-resistant steel, which is equivalent to 15CrMo in China.
3. TIG-R30 welding wire and R307 welding rod can be used for welding.
