Description/描述

?VIM-VAR 52100 is a high-carbon, chromium-bearing alloy steel possessing deep hardening characteristics as well as high wear resistance. VIM-VAR 52100是含碳量含鉻量高的合金鋼，能被深度硬化，具有高抗磨損性能。

To meet the exacting requirements of bearing manufacturers for a clean steel with uniform microstructure, it is produced by vacuum induction melting (VIM), followed by vacuum arc remelting (VAR).?為了滿足軸承制造商對具有一致微觀結構的清潔鋼的需求，52100由真空感應熔煉加上真空電弧重熔得來。

Normalizing/常化

Heat to 1700°F (927°C), then air cool.加熱至1700°F (927°C)，然后空冷

Annealing/退火

Heat uniformly to 1425°F (775°C), then cool slowly in the furnace. Brinell hardness will be 223 maximum with a spheroidized structure.均勻加熱至1425°F (775°C)，然后緩慢爐冷。布氏硬度最大將達到223，具有球化結構。

Hardening/硬化

For sections up to 1" (25.4 mm) in diameter or thickness, heat to 1530/1550°F (832/843°C), then oil quench.?橫截面直徑或厚度在1" (25.4 mm)以下的，加熱至1530/1550°F (832/843°C)，然后油淬For sections over 1" (25.4 mm) in diameter or thickness, heat to 1475/1500°F (802/816°C), then water quench. An interrupted quench from water into oil as soon as the first violent vibration on the tongs is over is suggested.?橫截面直徑或厚度在1" (25.4 mm)以上的，加熱至1475/1500°F (802/816°C)，然后水淬。

Tempering/回火

Forging鍛造

VIM-VAR 52100 should be forged from a temperature of not over 1950°F (1066°C).?鍛造VIM-VAR52100時溫度不能超過1950°F (1066°C)

Machinability切削

For most machining operations a spheroidized structure is preferred.?球化結構適合絕大多數切削加工。
Cold drawn annealed VIM-VAR 52100 bars possess a machinability rating of 37% of AISI B1112 steel and cut at a speed of 63 sfm. The character of the chips is continuous and stringy.?冷拉退火的VIM-VAR52100棒料具有AISI B1112鋼37％的切削性能，切削的速度是63 sfm。碎片有延續性。
Hot rolled annealed bars have a machinability rating of 45% of AISI B1112 steel.?熱軋退火的棒料具有AISI B1112鋼45％的切削性能
