JIS G3455 STS410 seamless steel pipe is made of a whole piece of metal. There is no seam on the surface of the steel pipe. There are many kinds of seamless steel pipe materials, so its use is very wide.
1、 Tensile strength of JIS G3455 STS410 seamless steel pipe
The stress obtained by dividing the greater force (FB) that the specimen bears during the tensile process by the original cross-sectional area of the specimen（σ） Which is called tensile strength（σb) The unit is n / mm2 (MPA). It indicates that the metal material has greater resistance to failure under tensile force.
2、 Yield point of JIS G3455 STS410 seamless steel pipe
The yield point of JIS G3455 STS410 seamless steel pipe with yield phenomenon is the stress when the specimen can continue to stretch without increasing the tensile force (keeping constant). If the force decreases, the upper and lower yield points should be distinguished. The unit of yield point of JIS G3455 STS410 seamless steel pipe is n / mm2 (MPA).
3、 Upper yield point of JIS G3455 STS410 seamless steel pipe
The larger stress of JIS G3455 STS410 seamless steel pipe before yielding and the first decrease of stress; Lower yield point: the smaller stress in the yield stage when the initial instantaneous effect is not taken into account.
