Product Presentation Low carbon steel ball AISI 1010/1015/1020( C10-C15-C20 ) Balls in these materials are case-hardened only (surface heat treatment ). Low carbon steel balls offer considerable savings in all those applications which do not require the use of through hardened balls. The most common applications include furniture wheels, beatings for drawers, locks, grease nipple, sliding blocks, toys. Diameter: From 2mm to 50mm Precision grades:ISO 3290� G40-100-200-AFBMA� G500/G1000 Equivalent materials to international standards:AISI 1010/1015/1 020-W1.0010-JIS SWRM 12-ASTM A/29 Chemical Composition % Material Type C Mn P S AISI 1010(C10) 0.10 0.30 0.45 0.45 AISI 1015(C15) 0.15 0.30 0.45 0.45 AISI 1018(C18) 0.18 0.30 0.45 0.45 AISI 1020(C20) 0.20 0.30 0.45 0.45 Hardness index(surface case hardening) :HRC 55/59 Mechanical properties: Critical Tensile Strength: 37kgf/m Compression Strength: 30kgf/m Modulus or Elasticity: 19.693kgf/m Specific Weight: 7.85kgf/m STRICT PRODUCTION PROCESS A. Raw material--Wire drawing--Cold heading--Flashing--Heat treatment--Grinding--Lapping 1--Lapping2--Lapping3--Washing--Checking. All balls must be passed the procedure of passivity. Each procedure have professional inspector. They will check steel balls each two hours to insure the correction diameter and good surface of SAIGE steel ball. B.Our high precision bearing steel balls is G10.(Diameter variation is in 0.25um) Following is our inspection standard of G10 steel balls: 1.Each size of chrome steel balls have their own standard balls which are imported from Japan. 2.These standard balls were stocked into antitrust oil at the temperature 20� C. 3.Our size measurement instrument's precision is up to 0.1um.Also import from Japan. 4.We will check the diameter, hardness, surface, deviation from spherical, vibration value and so on.
