High temperature affect the bearing of 304 and 440 stainless steel material of high temperature bearing 304 and 440 stainless steel material stainless steel high temperature bearing now divided into 440304316 these three materials, the first two are common high temperature stainless steel bearing.
440 material must be magnetic, that is, the magnet can accommodate.
304 and 316 belong to micro magnetic (
Many people say he is not magnetic that is not correct)
Magnet is not suck, but you can feel a little suction.
Common high temperature bearing of 304 stainless steel material.
So high temperature bearing 304 and 440 stainless steel material which good?
304 is made of stainless steel, the price is 440 will consider low corrosion resistance and mechanical properties, the comprehensive performance, so as to get more widespread application.
But the disadvantage is that can't stop further heat treatment to change its performance.
440 is high strength cutting steel (
Endnotes A, B, C, F, etc.
After proper heat treatment, belongs to the hard stainless steel.
Common application example is the 'blade'.
