4 pattern of representation

4.1 General Under normal circumstances, due to the need to be machined (such as grinding) parts after heat treatment, heat treatment and so marked should be considered in the design of the machine Processing (eg grinding) on parts. Carbonitriding parts hardness coating layer with reduced thickness decreases, particularly surface hardening, hardening Hardening, hardening and nitriding fused parts. Therefore, we must take into account the heat treatment process requires appropriate machining allowance. If there is no separate Drawings will be described in the relevant drawings shall be marked with a suitable heat treatment prior to or subsequent to illustrate the machining information. For example, in the pattern GB/T 24743-2009/ISO 15787.2001 ......
