FOB Price:US $20-150 / Kilogram. 42crmo4 material products42CrMo4 +QT Steel (1.7225 Material) 42CrMo4 material (1.7225 steel) is an European standard alloy steel,the delivery condition of this steel is mostly tempered and quenched,it has high strength,high toughness,good hardenability,temper brittleness,high fatigue limit,good impact resistance after quenching and tempering,and good low temperature AISI 1045 Steel Bar Plate - JIS S45C - DIN C45 - Songshun AISI 1045 Steel Round Bar Sheet Plate, JIS S45C, DIN C45. AISI 1045 steel is high-quality medium-carbon steel with high strength. It also can be called JIS S45C and DIN C45 steel. It is usually used in normalized condition because of its bad hardenability. It needs to be quenching and tempering treatment to get higher mechanical performance.
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. Low-temperature impact toughness is also very high, no obvious temper brittleness. It is mainly used after quenching and tempering state. It is used to manufacture high-strength parts under impact loads and the fittings with large cross-sections and B7 4140 42crmo4 1.7225 Alloy Steel Bar Square Bar - Buy B7 4140 42crmo4 1.7225 Alloy Steel Bar Square Bar , Find Complete Details about B7 4140 42crmo4 1.7225 Alloy Steel Bar Square Bar,4140 Steel Bar,Alloy Steel Round Bar,Square Bar from Steel Round Bars Supplier or Manufacturer-Ningbo Chenglong Special Steel Co., Ltd.

Grade Guide:AISI 4140 Steel Metal Supermarkets - Steel Jun 19, 2018 · AISI 4140 steel is a low alloy steel containing chromium, molybdenum, and manganese. It is widely used across numerous industries and is an excellent material choice due to its toughness, high fatigue strength, and abrasion and impact resistance. Not many grades can match the versatility and usefulness of 4140.
Dear Sir, My query is about qualifying a procedure for the combination, EN19 (AISI 4140) to Weldox (S690QL) As youve stated in this article, qualifying 4140 in annealed condition is easier and S690QL properties will deteriorate on PWHT, What would be the heat treatment condition for the both materials then prior to qualifiaction to avoid PWHT42CrMo4 / 1.7225 - SteelNumber - Chemical composition Vickers hardness ( HV):(+QT) 340 - 490. Properties of steel 42CrMo4 (1.7225) Weldability:Bad weldability due to the high crack danger. Hardenability:Medium-good hardenability, suitable for hot purposes till a temperature of 500 C. It can be hardened in oil. Equivalent grades of steel 42CrMo4 (1.7225) Warning!
