Sometimes magnetism can result in the reject for stainless steel castings.
First austenite is not magnetic, meanwhile martensite is magnetic.
Some austenite can change to martensite during cold machining process. so these stainless steel will be with some magnetism.
If the process is not enough correct during the heat treatment, some austenite can also change to martensite. then the stainless steel will be magnetic.
How to avoid or remove magnetism for stainless steel.
First of all, Refidus will choose the correct and qualified stainless steel material.
We control the heat treatment well, and avoid wrong cooling method during heat treatment process.
Solution treatment can also remove manetism for stainless steel.
China OEM silica sol investment manufacturer, Qingdao Refidus is good at precision stainless steel OEM castings, we are more than pleased to cooperate with you at any time and method.
