Chemical composition of 13crmo44 specification equivalent material

Composition characteristics of 13CrMo44 specification product: (1) Low carbon: Due to high requirements for toughness, weldability and cold formability, its carbon content does not exceed 0.20%. 2) Add manganese-based alloying elements. 3) Adding auxiliary elements such as niobium, titanium or vanadium: a small amount of niobium, titanium or vanadium forms fine carbides or carbonitrides in the steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of the steel.

From the name, we can clearly know that seamless pipe is seamless steel pipe, which is different from welded pipe. Seamless pipe is actually a kind of steel with hollow section. 13CrMo44 specification, Seamless pipe has many advantages, such as: 1, the compressive capacity of seamless pipe is very good, the place with high bearing strength will not crack, and its bearing capacity is very good. 2. Seamless pipe has no welding point, so it is more corrosion-resistant and can bear larger pressure.

Material 1.0473 is a pressure-vessel steel grade. Its tensile strength is between 510 and max. 650 N/mm².This grade is well weldable. 1.0473 is being used for steam boilers as well as pressurized vessel constructions. Equivalent: DIN P355GH, DIN 19Mn6, 13CrMo44 specification, ANFOR A52CP, UNI FeE355-2, JIS SGV410, JIS SGV450, JIS SGV480, JIS SPV355, UNS K02700.
