It stipulates that the deformation of stainless steel standard parts at the quenched and tempered place is small, the heat treatment temperature range is wide, the precision spring is wide, the over-temperature sensitivity is small, the carburization sensitivity is low, and the heat treatment crack tends to be inferior. It can be produced at first, but in large batches, it seems to be more conducive to production. (3) Supply can ensure that the selected raw materials should take into account the resources and actual supply conditions in my country, and try to avoid the use of imported raw materials, and the types, specifications and models should be avoided and centralized as much as possible to facilitate the procurement management process. (4) Reasonable and reasonable requirements to select raw materials with simple processing process, high output rate and low cost. Considering the characteristics and service life, try to use cheap raw materials for plastic machinery and equipment to control costs. Seven, the actual consideration of abrasive material selection factors In the specific design and production of abrasive tools, the actual material selection should be comprehensively analyzed, and the following factors should be considered. (1) Standard elements in the work of the abrasive tool 1. The size and speed of the load-bearing force (impact condition) are large, and the original stainless steel casting material requires high compressive strength; if the impact is large, the ductility is required.
