Aluminothermic welding of austenitic manganese steel |
摘要 |
A method of aluminothermic welding of members of austenitic steel containing by weight 10 to 20% manganese, 0.5 to 1.5% carbon and 0 to 5% nickel, and particularly low carbon austenitic steels containing by weight 14 to 17% manganese, 0.5 to 1.5% carbon and 0 to 5% nickel, comprises using a particulate mix for forming the aluminothermic steel, which mix is substantially free from phosphorus and silicon and a mould whose body material is predominantly a non-silicon material.
