Product Description
SAE4140+QT EN10083-3 Cold drawing Precision steel tube
4140 alloy steel material is a high-quality Quenched and Tempered Alloy Structural steel, It belongs to the high-quality medium carbon alloy steel, Oil Quenched & Tempered Hardness is 28-34 HRC.4140 Annealing delivery hardness less than 250HB.
- These chromium-molybdenum alloys are among the most widely used and versatile machinery steels. The chromium content provides good hardness penetration and the molybdenum imparts uniformity of hardness and strength. They respond readily to heat treatment and tensile strengths in order of 170,000 psi (1172 N/mm2) for small sections and 140,000 psi (965 N/mm2) for larger sections are attainable, all combined with good ductility and resistance to shock. They may be used in both high and low-temperature applications and also in sour gas environments with appropriate heat treatments.
- In the hardened and tempered condition, these steels possess good wear resistance which may be considerably increased by flame or induction hardening. Alternatively, they may be nitrided. In the annealed condition, bars are supplied to a hardness of HB 207 approximately. Some sizes may be calcium-treated. The 4140 Product is also available in a precision ground surface finish (25RMS Max).
