Properties and Applications
GT35 有很好的耐磨性及較高的硬度,但不耐高溫與腐蝕。用于冷鐓、冷沖、冷擠、冷拉等模具 、鏜桿、軋輥滾壓工具、機(jī)器零件,特別適于作耐磨零件等。
It has good wear-resistance and rather high hardness,but it is not well resestant to high temperatures and corrosion.It is used in manufacturing cold heading and punching dies,cold extruding and drawing dies,boring hars,roll rings and rolling tools,and measuring and fixing instruments,and it is especially suitable for wear parts,etc.
GW1 具有較好的機(jī)械綜合性能和耐磨性。適用于冷沖、冷墩、冷拉、冷擠、整形等模具以及各種耐磨零件、剪切和量卡工具等到。
It has good comprehensice mechnical performance and wearresistance. It is suitable for making cold punching and heading dies clod extruding and drawing dies.And reshaping too ls and various wear parts,shearing tools and measuring and fixing instruments.
R5 有較高的硬度和耐磨性,具有明顯的回火二次硬化現(xiàn)象,抗回火、抗氧化,肯有一定的抗蝕性。適用于溫?zé)嶙髂>吆涂寡趸?、抗蝕、耐磨同時要求的工件,如刮片、密封環(huán)等。
It has high hardness and is well wear-resistanct.It has an obvious trend of hardening after tempering for a second time.It is resistant to tempering and some
