Product Description

EN10253-4 1.4306 X2CrNi19-11 TYPE B 90DEG 3D ELBOW 
 

The EN 10253-4 standard is a production specification document for stainless steel butt welded pipe fittings, which specifies the dimensions, tolerance, and material properties of stainless steel butt welded pipe fittings. Stainless steel butt welded pipe fittings are widely used pipeline connecting components in the industrial field, made of stainless steel material, with corrosion resistance and high temperature resistance.

Performance Requirement

The EN 10253-4 standard for stainless steel butt welded pipe fittings also specifies the mechanical properties and testing methods of the fittings, such as tensile strength, yield strength, elongation, etc., to ensure that the fittings can withstand sufficient pressure and stress during use.

The EN10253-4 stainless steel butt welded pipe standard includes more than 20 European standard stainless steel materials, including X2CrNi18-9(1.4307),X2CrNi19-11(1.4306),X2CrNiN18-10(1.4311),X5CrNi18-10(1.4301),X6CrNiTi18-10(1.4541),X6CrNiNb18-10(1.4550),X1CrNi25-21(1.4335),X2CrNiMo17-12-2(1.4404).Stainless steel material.The following is a table of chemical composition and mechanical performance parameters for each material grade.

d	The maximum temperatures are for guidance only.
e	w = water ; a = air ; cooling sufficiently rapid.
f	When tested in accordance with EN ISO 3651-2 (Appropriate method, A or B or C, shall be as indicated) up to the limit temperatures indicated in the last column of table 8.
g	In delivery condition. (Normally not fulfilled in the sensitized condition).
h	For the delivery conditions W 0, W 1 and W 2 which do not include solution annealing, the upper Rm   limit may be exceeded by 70 MPa .
i	Up to these temperatures, the material should, within 100 000 h, not have changed so as to show susceptibility of intergranular corrosion, when tested in conformity with EN       ISO 3651-2.
