4140 High Tensile Steel Interlloy Engineering Steels

4140 High Tensile Steel 4140 is a 1% chromium - molybdenum medium hardenability general purpose high tensile steel - generally supplied hardened and tempered in the tensile range of 850 - 1000 Mpa (condition T).4140 is now available with improved machinability, which greatly increases feeds and/or speeds, while also extending tool life without adversley affecting mechanical properties. CNS-SCM440 - Ju Feng Special Steel Co., Ltd.SCM440 is medium carbon chromium molybdenum alloy steel, which is an alloy steel containing chromium and molybdenum. It has the advantages of stable composition, low harmful elements, high steel purity, small decarburization layer and few surface defects. It is easy to be spheroidized and has low cold cracking rate.

The advantages and industrial applications of JIS SCM440

The JIS SCM440, SAE 4140 and 42CrMo Alloy Steel Pipe s that contains the mixture of molybdenum and chromium in the carbon steel are chrome molly pipes. The inserted chromium and molybdenum impart the characteristic properties in the pipes. The molybdenum in the alloy is important in the enhancement of the strength of the steel.AISI SAE 4140 Steel - JIS SCM440 - DIN 1.7225 - Songshun Jul 31, 2019 · AISI 4140 Steel Round Bar Sheet Plate, JIS SCM440, DIN 1.7225 AISI 4140 alloy steel round bar sheet plate has high fatigue strength and low notch sensitivity.
