Material Description

Material Number Material Name Material Number (single) Standard Standard Status Country VDA 231-106 classification Application temperature [°C]
1.6562 (VdTÜV WB 380 : 2001-09) 40 NiCrMo 8 4 1.6562 VdTÜV WB 380 : 2001-09 Valid Germany 1.1.1 -10 - 350 1)
1) Remark: Valid for steel for shape and rod, forging for screws and nuts, nuts and grommet steel for rolling and forging 40 NiCrMo 8 4 in quenched and tempered state I, II, III no welding, no forming, because the delivery state is the final state, so only cutting possible Application: in range of -10°C to 350°C - for pressure tanks according to TRB 100 and AD-Merkblatt W 7 - for steam boiler according to TRD 106 - in nuclear power engineering as far as nuclear rules or object-related specifications permit smelting: - oxygen blowing process - electric arc process state of removing oxygen: becalmed
