Material Description

Material Number Material Name Material Number (single) Standard Scope Standard Status Country VDA 231-106 classification
2.4879 (DIN 17465 : 1993-08) G-NiCr28W 2.4879 DIN 17465 : 1993-08 DIN 17465 : 1993-08 replaced by DIN EN 10295 : 2003-01 Replaced Germany 3.4 1)
1) Remark: The heat-resistant cast material G-NiCr28W is suitable for temperatures between 1150 and 1200 °C in air or in an oxidizing atmosphere depending on the sulphur content and for temperatures between 1100 and 1150 °C in a reducing atmosphere. Application for highy stressed furnace parts and hearth rolls that are exposed to a carbonizing atmosphere at an operating temperature of up to 1200 °C. The weldability is good.
