9.525mm(3/8"), 5mm 6mm 7mm 10mm Solid stainless steel metal ball for bearing
Introduction
Stainless steel balls are usually produced through a forging
process. At this stage, commonly used stainless steel balls are
made of 201, 302, 304, 316, 316L, 420 and 440C.
Definition: Steel with a chromium content of more than 12% and
resistance to chemical substances.
Principle: Stainless steel does not rust, but it is not easy to
rust.
The principle is that by the addition of chromium elements, a dense chromium oxide layer is formed on the surface of the steel, which can effectively block the re-contact between the steel and the air, so that the oxygen in the air cannot enter the steel, thereby achieve the effect of preventing steel from rusting.
We mainly export stainless steel balls (201, 304, 316, 420, 420C,
440C, 430). It also produces chrome steel balls (AISI52100, 100CR6,
GCR15), carbon steel balls (1015, 1010, 1045, 1085) and other
materials of various materials.
Our steel balls are used in many industrial fields, such as precision bearings, automotive parts (brakes, steering gears, spools), bicycles, agitators, electrical appliances, sliders, quick connectors, machine tools, locking mechanisms, conveyor belts, roller skates, pens , Pumps, casters, measuring instruments, valves, etc.
Stainless steel ball performance
Stainless steel ball 440/440C hardness reaches 56-58 degrees, it have magnetic, good corrosion resistance, wear resistance and toughness. It is mainly used in industries that require high accuracy and rust resistance, such as bearings, stamping/hydraulic parts, Valves, motors, high-precision instruments, seals, refrigeration equipment, aerospace high-precision mechanical parts, petroleum. Specification: Φ1.0—Φ30mm, 440C stainless steel ball.
Stainless steel ball 316
Application areas:
316 stainless steel ball is a relatively demanding product, usually used in special industries such as medical equipment, chemical industry, aviation, aerospace, perfume bottles, sprayers, valves, nail polish, human accessories, mobile phone panels.
Features:
Austenitic steel is currently the most high-end steel ball industry, HRC ≤ 26, suitable for industries with high anti-corrosion requirements, all properties are better than 304 stainless steel balls.
Comparison:
316L stainless steel ball is softer and tougher than white, so it is usually used for human body jewelry.
