Material name: China 20CrMnTi alloy carburizing steel
Materials are: steel
The major manufacturers: Other
Physical properties: tensile strength σb (MPa): ≥ 1080 (110)
Availability hardness: ≤ 217HB
Typical Applications: Cold mold:
1) for the manufacture of cross-section <30mm in under high speed, medium or heavy load, impact and friction of the important parts, such as gear, gear ring, gear shaft crosshead.
2) sets of aluminum extrusion die for, D16 and D20-type suppression of the cold wire sets aluminum extrusion die.
Plastic Mould Steel:
1) for small precision cavity inserts can be used to add surface hardness of carburized to improve the wear resistance.
2) The larger the wear by the larger load and the production of large quantities of mold.
Related Description: 20CrMnTi is the good performance of the alloy carburizing steel, high hardenability, carburizing quenching with a hard and wear-resistant surface and tough core part, has a high low temperature impact toughness, welding of medium, is After fire, cutting good.
≤ 960 ℃ when the fine grain structure, in common carburizing temperature, long-term heating, no grain growth tendency, very little retained austenite after quenching, so it has high strength and wear resistance, cutting Good performance, the main performance and 20CrMnTi and 20CrNi similar.
Automobile transmission gear with its manufacturing is in hardenability carburizing steels Cr Mn Ti steel, the hardenability of high hardenability in the case of guarantee, with high strength and toughness, especially those with higher Low temperature impact toughness .20 CrMnTi treatment of case hardened steel. good workability, in particular processing small deformation, fatigue resistance is very good.
When doing a slightly different plastic mold steel:
1) Availability Status: normalized
2) the critical temperature: Ms = 374 ℃
3) quenching and tempering specification: austenitizing temperature of 880 ℃, time of 25min, the grain size 7-8.
