EN 34CrNiMo6 Steel is an important alloy engineering steel grade as per BS EN 10083-3:2006. 34CrNim06 steel has high strength, high toughness and good hardenability. EN / DIN 34CrNiMo6 alloy steel has the stability of resistance to overheating, but the white sensitivity of 34CrNiM06 is high. It also has the temper brittleness, so the weldability of 34CrNiMo6 material is poor.

High Tensile Steel, AISI 4140, SCM440, 42CrMo4, ASSAB 709, 7225, EN19, SCM4: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). Longitudinal Submerged Arc Welding LSAW Steel Pipes Longitudinal submerged arc welding is a special welding technology used in pipe production. Because of high internal or external pressure, the final product needs high wall thickness. Considering this, the main applications of pipeline LSAW Steel Pipe s include oil, natural gas, natural gas, central heating, water supply, sewage treatment and
welds Stainless steel / steel, stainless steel / stainless steel, aluminum / steel and steel / steel are often obtained for different requirements [3,4], among which is a welding between a tempered steel tempering (42CrMo4) with a low steel on carbon (X70) which seems to be very interesting for the realization of a GMA crane in our center. Steel Grade Equivalent Table (EN, SAE/AISI, UNS, DIN, BS Steel Grade Equivalent Table (EN, SAE/AISI, UNS, DIN, BS, UNI, JIS) The table below compares common grades of materials from various international specifications. Note that materials compared are the nearest available grade and may have slight variations in actual chemistry. Comparison of steel grades by chemistry. EN #.
Welding 4140 is a lot like welding 4130 which is a lot like welding plain old steel. Except for being more crack sensitive and therefore needing a preheat before welding on certain applications, the puddle looks very much the same as welding plain carbon steel thats because the composition is so similar. 4130 and 4140 are low alloy steels. [MW:8388] Suitable welding electrode for 42CrMo4 V Nov 26, 2010 · As discussed forwarding the related information for selecting the suitable welding electrode on repair welding of 42CrMo4 V material (DIN 1.7225 / SAE 4140).
