The seamless carbon steel pipe for ships (gb5213-85) is the seamless carbon steel pipe for the manufacture of class I pressure pipe system, class II pressure pipe system, boiler and Superheater of ships. sa573 gr 70 carbon plate export. The working temperature of carbon steel seamless pipe wall shall not exceed 450 ℃, and that of alloy steel seamless pipe wall shall exceed 450 ℃.
It is understood that wear-resistant plate is a product type with relatively bright brightness in wear-resistant steel plate. sa573 gr 70 carbon plate export, The wear-resistant plate has large hardness and is widely used. It can be applied in most of the engineering and mechanical industries. The performance of wear-resistant plate is good, and the direct reason for its wide use is that the density is relatively large.
The strengthening mechanisms in metals mainly include solid solution strengthening, dislocation strengthening, fine grain strengthening, and second phase (precipitation and dispersion) strengthening. Alloying elements have the most significant strengthening effect on steel in the quenched and tempered state, because it makes full use of all four strengthening mechanisms. Martensite is formed during quenching, and carbides are precipitated during tempering, resulting in a strong second phase strengthening and greatly improving toughness. Therefore, obtaining martensite and tempering it is the most economical and effective comprehensive strengthening method for sa573 gr 70 carbon plate export.
20# seamless steel pipe chemical composition: C: 0.07-0.23, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.25, Ni: 0.30, Cu: 0.25. 20# seamless steel pipe mechanical properties: recommended heat treatment temperature: 910℃, tensile strength: 410 MPa, yield strength: 245 MPa, elongation: 25%, impact energy is not required. 20# seamless steel pipe hardness is higher than 10# seamless steel pipe. sa573 gr 70 carbon plate export, 20# seamless steel pipe has good weldability, no temper brittleness, and its machinability can be improved by water quenching. 20# seamless steel pipe can be used to make welded components, as well as parts with small load after forging, hot stamping and cutting.
