Diameter size：25mm-800mm
Product descripiton：
Austenitic Steel 302, 304/304L, 316/316L: Most common hollow ball material. Good for valve and float ball.
Martensite Steel 420/420C: HRC 55 and above. For applications that need hardened material.
Duplex Steel 2205/2507: Featured with improved strength over austenitic stainless steel and also improved localized corrosion resistance, particularly pitting, crevice corrosion and stress corrosion cracking. Comparing with austenitic stainless steel, they also with lower thermal expansively and higher heat transfer rate. The 2507 is also called “SuperDuplex” due to its higher corrosion resistance.
Carbon Steel C1020:To be used as cores for coating processes. Common coating material including rubber, plastic, etc.
Bearing Steel 52100/100Cr6:High precision finish, G10 and above. Substitute solid balls in ball bearing applications. 60% weight advantage compare to conventional solid balls.
Payment: T/T or L/C at sight
