laser welding wire

LST-SKD610.2mm/0.3mm/0.4mm/0.5mm/0.6mm - HRC 40 43can welding zinc, aluminum die casting mould, hot-gas stamp die, copper-aluminum hot-forging die. It enjoy a good properties of heat, abrasive and chap resisting.Normally the hot chamber die casting mould always carry the crack. That’s caused by thermal stress. Also maybe because the surface oxidation or the corrosion of die casting raw material. So the heat treatment should adjust to proper hardness, otherwise, it will affect its life span. The hardness too low or too high is not good for use.LST-RNO18apply to the machine parts and tools. It enjoy a feature of high resistance to corrosion, high mirror polish after finish, good fusion welding, high toughness and deformation resistance.With this material, after welding, the welding part be more easy for grinding. And it is with moderate compact. So it fits for more difficult/higher requirement working face. And apply to thewelding of non-alloy or low alloy material.With this material, after welding, thewelding part can go through grinding machining treat with carbon tool steel. And it can even resist working temperature of 450 degree by treat with non-alloy steel.Also apply to the welding of the parts which is rust caused by air, water, vapour or non resistant parts. And it can reach burning resistance to 900 degree.Expansibility reach to 900 degreeStandard Evaluation: Raw material type 1.4502 DIN EN 14700 S Fe 7 DIN EN ISO 14919 X 8 Cr Ti 18Chemical component:CSiMnCrTi0.100.700.3017.50.60The chemical component depends on the soldering parameter.LST-60 0.2mm/0.3mm/0.4mm/0.5mm/0.6mm - HB 200Applied to the loyal brand steel, iron pattern, shoe mould, soft-steel soldering, S45C, S55C repairing. Easy engraving andetching. LST-CUS .0.2mm/0.3mm/0.4mm/0.5mm/0.6mm - HB 200·has a good mechanical properties which can be applied to the argon welding copper. This enjoy a widely use, can soldering for electrolytic strip, copper alloy, beryllium copper, steel, bronze, cast iron, normal copper parts.LST-OH10.2mm/0.3mm/0.4mm/0.5mm/0.6mm - HRC 52 57 can be applied to oil cylinder, stamping & cutter die, measure gauge, drawing die, piercing punch. It is widely used in hardware stamping and jewels embossing die. Commonly used in special tool steel. It’s abrasive resisting.LST-Cr0.2mm/0.3mm/0.4mm/0.5mm/0.6mm - HRC 55 57can be applied to chrome steel, stamping & cutter mould,cold forming die, cold drawing die, punch. High hardness, high toughness, good wire cutting. Pre-heating before welding. Post-heating after welding.Notice: Because this is an alloy material, not stainless steel wire. So if not for good-keeping, it will suffer for rusting. In such case, it will not affect the quality. User can use the abrasive paper to polish the surface rusty scale..
