The journal is cast from material 42CrMo with high hardness, which requires the part to be free of internal looseness, air holes and sand holes.
This is Full-range machined by machining centers, which has high requirements for machining capacity. Ensure that the part has enough machining allowance for further machining, so as to avoid the problem of “black skin” on the surface.
Due to the high hardness and the difficulty of the machining , only 5 parts can be machined a day.
100% magnetic particle inspection and ultrasonic inspection are carried out to ensure the internal quality of each part in the end.
Ningbo Yinzhou Gain Machinery Co.,Ltd (Metaphönix GmbH ) not only specializes in machining from steel plate/bar/pipe, but also has considerable expertise and rich production experience in the field of casting machining.
Why is solution treatment necessary for stainless steel, and why are more and more products now requiring solution treatment?
Solution Treatment of Stainless Steel To understand why stainless steel requires solution treatment, we first need to clarify the purpose of solution treatment, its functions,
