Impact Resistance Steel 1.2355/50crmov13-15 S7 Sheet Alloy Tool Plate Steel

                                               DIN 1.2355 | ASTM S7 Hot Work Tool Steel Quick Details1: AISI S7 steel introduction    AISI S7 tool steel is a shock-resistant air hardening steel. AISI S7 steel has exceptional impact properties plus the highest hardenability of shock resisting grades of tool steel. Steel S7 also possesses good softening resistance at high temperatures which gives it hot work capabilities. Since S7 steel hardens in air, it is also safe and stable in heat treatment.    AISI S7 tools steel has an unusual combination of properties, making it suitable for an extremely wide range of tool and die work - where shock-resistance, medium hot-work properties, or ease of machining and heat-treatment are most important. 2: AISI S7 Steel equivalentCountryChinaJapanGermanyUSAUKStandardGB/T 1299JIS G4404DIN EN ISO4957ASTM A681BS 4659Grade  1.2355/50CrMoV13-15S7/T41907 3: AISI S7 steel chemical compositionGradeCSiMnPSCrVMoS7/T419070.450.550.201.000.200.900.030.033.003.50-0.351.301.801.2355/50CrMoV13-150.450.550.200.800.500.900.030.023.003.500.150.351.301.704: AISI S7 steel mechanical properties    The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT.

AISI S7 Tool Steel Heat TreatmentAnnealing    Anneal in a protective atmosphere. Heat rapidly to 1500 to 1550°F and hold at that temperature for one and one-half hours for each inch of greatest thickness. To obtain best machining properties, cool slowly to 1000°F, and then air-cool. This annealing procedure should produce a hardness of Brinell 197 max.Stress Relief S7 steel Material: When desirable to relieve the strains of machining, heat slowly to 1050°-1250°F, allow to equalize, then cool in air.Hardening    Preheat: Warm steel S7 slightly before charging into the preheat furnace 1200°-1300°F, prior to hardening.Harden: 1750°F. Quench S7 tool steel in air if cross section is 2-1/2″ or smaller; sections 2-1/2″ to 6″ should be oil quenched to black (1000°F) followed by air cooling to 150°F. Larger cross sections of S7 steel should be oil quenched to 150°F.    Quench: Quench in still air or dry air blast.    Temper: Tool steel S7 is normally tempered one hour per inch of section thickness to desired heating rate of 2 hours per inch. Cool in air to room temperature between the two tempers. The tempering temperature varies according to the intended use. Suggested: For cold-working and similar applications, the recommend400°-500°F. Hot working applications: apply a tempering temperature of 900°-1000°F. Never temper at less than 400°F. 7: Delivery condition    For hot forged or hot rolled bar, usually the delivery condition is hot forged or rolled, annealed, rough turned.    For hot forged plate, usually the delivery condition is hot forged, annealed, milled surface.    For hot rolled plate, usually the delivery condition is hot rolled, annealed, black surface.      Hunan Qilu Industrial ship out steel round bar and plate to many different counties every month, such as Malaysia, Singapro, Vietnam, India, Korea, Indonesia, Australia, Ireland, Italy, Greece, Israel, Dubai, Saudi Arabia, Mexco, Colombia, Argentina, Peru, South Africa...1: Main Product:GB     GB/T 1299       JISJIS G4404DIN (W-Nr.)DIN EN ISO4957AISI/ASTMASTM A681BSBS 4659Cold Work Tool SteelCr12SKD11.2080/X210Cr12D3 Cr5Mo1VSKD121.2363/X100CrMoV5A2/T30102BA2Cr12MoV 1.2601D5 Cr12Mo1V1SKD111.2379/X153CrMo12D2 X210CrW12SKD21.2436D6 9CrWMnSKS31.2510/100MnCrW4O1 9Mn2V 1.2842 / 90MnCrV8O2B025CrNiMoSKT41.2713L6/T61206BH224/5Hot work Tool Steel  1.2355/50CrMoV13-15S7/T41907 5CrNiMoV 1.27146F3 5CrNi4Mo 1.27676F7  SKD71.2365/32CrMoV12-28 H10/T20810BH104Cr5MoVS
