SF-2000 LQ40 ESR模具鋼是加拿大多利科 (SOREL FORGE STEEL)模具鋼。SF-2000 LQ40 ESR模具鋼是一款預(yù)硬模具鋼，為電渣重熔鋼，其預(yù)硬狀態(tài)下的洛氏硬度為38-42HRC，布氏硬度為355-390HB，抗拉強(qiáng)度為1202-1322MPa。
SF-2000 LQ40 ESR模具鋼具有很好的沖擊強(qiáng)度和良好的回火穩(wěn)定性，大尺寸工件硬度非常均勻。
SF-2000 LQ40 ESR模具鋼的特性如下：
? 拋光性極佳；
? 好的機(jī)械加工性能；
? 硬度非常均勻；
? 高純凈度，組織均勻；
SF-2000 LQ40 ESR模具鋼100%經(jīng)過(guò)非常嚴(yán)格的超聲波測(cè)試，能夠確保非常高的質(zhì)量。
SF-2000 LQ40 ESR模具鋼具有非常均勻的成分分布和金相組織。均勻的回火馬氏體和貝氏體組織保證材料具有優(yōu)異的拋光特性。SF-2000 LQ40 ESR經(jīng)一臺(tái)5000噸寬體鍛壓機(jī)進(jìn)行鍛造，從而確保鋼坯中心在鍛造過(guò)程中能夠達(dá)到最大的變形。SF-2000 LQ40 ESR模具鋼在鍛造過(guò)程中經(jīng)過(guò)特別的致密化鍛打過(guò)程，確保了中心組織的致密度。SF-2000 LQ40 ESR模具鋼是一種優(yōu)異的蝕紋材料，電渣重熔工序去除了幾乎所有的偏析，SF-2000 LQ40 ESR模具鋼的高純凈度保證了高質(zhì)量表面。高淬性確保了加工表面的硬度。超低硫含量，非常均勻的顯微組織，保證了SF-2000 LQ40 ESR模具鋼在經(jīng)過(guò)合理的拋光工序后會(huì)達(dá)到SPI A-1級(jí)的表面質(zhì)量。
