23.812mm(15/16"), Hot Sale High Quality Stainless Steel Metal Ball For Bearing
Introduction
AISI 440C stainless steel ball
Profile
AISI 440C stainless steel balls provide maximum hardness, toughness and dimensional stability. They are highly resistant to rolling contact fatigue. 440C stainless steel ball is used under hardened conditions, its performance is similar to tool steel, and it is an ideal choice for anti-wear bearings (rolling bearings).
Characteristics
440C stainless steel balls reach the highest hardness after heat treatment: Rockwell C 58 to 62. The Hartford 440C stainless steel ball is passivated to remove free iron contaminants and facilitate spontaneous formation of a protective passive film.
Corrosion resistance
440C stainless steel balls generally have excellent resistance to weak acids, strong alkalis, food, fresh water and air.
Hardness
Rockwell C 58-62 is measured on parallel plates.
Size
The size is from 1mm to 50.8mm, and the grade is from 10 to 1000.
We are a multinational supplier of 440C stainless steel balls for applications include actuators, pumps and bearings.
Carbon Steel balls, Stainless Steel Balls, Chrome Steel Balls and Grinding Balls are the main products, which range varies from
0.5mm to 120mm and includes metric and inch sizes, standard ones, oversize and under size. Applicable for industrial usage such as hardware, bearing, wheels, bicycles, toys and chemistry, military ect. We are now the leading manufacturers of semi-precision balls from Grade 10 to Grade 2000 in China. And a regular supplier to some prominent companies all over the globe.
