24.606mm 31/32" Stainless Steel Balls HRc20-39 Precision Metal Balls

24.606mm(31/32"), High Precision Stainless Steel Metal Ball For Bearing

Introduction

International stainless steel marking method

The American Iron and Steel Institute uses three digits to indicate various standard grades of forgeable stainless steel.
① Austenitic stainless steel is marked with 200 and 300 series numbers.
② Ferritic and martensitic stainless steels are represented by numbers in the 400 series. For example, some of the more common austenitic stainless steels
It is marked with 302, 304, 316, and 310.
③ Ferritic stainless steel is marked with 430 and 446, and martensitic stainless steel is marked with 410, 420 and 440C.
Remember, dual phase (austenite-ferrite).
④ Stainless steel, precipitation hardening stainless steel, and high alloys with iron content less than 50% usually use patent names or brand names.

AISI 304/302 Stainless Steel Balls

Profile

Precision AISI 304/302 stainless steel balls Type 18-8 are used when conditions require corrosion performance and toughness not available in hardenable stainless steels. Principal applications are in couplings, valves and pumps.

Characteristics

Low magnetic permeability: annealed, 1.003; cold worked, 1.10; severely cold worked, 10.0. High tensile strength at elevated temperatures. 18-8 stainless steel work-hardens rapidly. AISI 304/302 stainless steel balls of this material are passivated.

Corrosion Resistance

Type 18-8 stainless steel balls resist attack by oxidizing solutions, foodstuffs, sterilizing solution and most organic chemicals. They are susceptible to attack by halogen acids and moderately resistant to the sulphur acids.

Typical Hardness

Annealed – Rockwell B 75-95. Not annealed – Rockwell C 25-39.

Ball Sizes

Available in sizes from 1.5mm to 50.8mm in grades 50 through 1000.
