Many customers often think that the magnets absorb stainless steel, verify its pros and cons and authenticity, do not absorb non-magnetic, that is good, genuine; suckers have magnetic, it is considered fake counterfeit goods. In fact, this is not right.
There are many types of stainless steel, which can be divided into several types according to the organizational structure at room temperature: 1. Austenite type: such as 304, 321, 316, 310, etc.; 2. Martensite or ferrite type: such as 430, 420, 410, etc.; austenite type is non-magnetic or weak magnetic, and martensite or ferrite is magnetic.
Usually used as a decorative stainless steel tube,Stainless steel stainless steel plate is mostly austenitic type 304 material, generally speaking is not magnetic or weak magnetic, but due to smelting chemical composition caused by fluctuations or processing conditions may also appear magnetic, but this can not be considered counterfeit or unqualified
What is the reason for this?
The above mentioned austenite is non-magnetic or weakly magnetic, while martensite or ferrite is magnetic. Due to segregation or improper heat treatment during smelting, it will cause a small amount of martensite or ferrite in austenitic 304 stainless steel. Body organization. In this way, 304 stainless steel will have a weak magnetic.
But in my company, LINAN DAYANG WELDING MATERIAL CO.,LTD, in order to make your sell easily, not to explain or convice with the end user hardly, all of our stainless steel welding electrode are not magentic even weak magnetic, we increase the degaussing process with stainless steel welding electrode or wires, to make your clients assured.
