Need suggestion for non-Magnetic steel
Q. Hello all, I'm working on a project and need some guidance. I am searching for a non-magnetic metal to replace 304 stainless. The application environment is 120 C, in 70w-140 oil, and the ID of the piece sit on a shaft rotating at 150 RPM (most have good wear resistance). Any ideas for a replacement material. ThanksBrunno Covolan

304 is normally non magnetic unless cold worked. Heat treatment will lower the magnetic level. Have you tried a professional degaussing unit?James Watts

If you want similar strength and hardness to 304 stainless, aluminium bronze C95400 is a good match.

You say Phosphor Bronze for bearing bushes etc; did you mean cast or wrought PBr. I'm asking since we have had material availability problems on items for actuator components; bearing bushes, thrust washers etc, which our suppliers are recommending a change from cast Leaded Bronze and Leaded Gunmetal to cast Phoshor Bronze. Also on offer, (and cheaper) is wrought Phosphor Bronze.
Could you advise on the relative wear resistance for these applications.

Non-magnetic Material for Bearing SlotSeptember 18, 2017
Q. I have a new product to market and need suggestions for best material for the bearing holder/sleeve. I have a 3/4" diam shaft and a standard bronze bushing over that and have placed that bronze through a SS washer pressed into the wall plate of 1/4" Al. It works but I am curious about the lifetime due to potential wear. This product is a magnetic separator for sands so these components must be non-magnetic but may be subject to dusty conditions and wear becomes an issue. What would be the best material to use for this application? The bronze can be easily replaced but the "pressed washer" needs to have a long wear life?Mike Robinson
