420 440 Stainless Steel Balls G10 G16 G20 8.731mm 0.34374" For Industry

8.731mm(0.34374"),SS 420, 440 grade 200 stainless steel balls for industry

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 adding chromium elements, a dense chromium oxide layer is formed on the surface of the steel, which can effectively prevent 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.

Classification: China National Standards (CNS), Japanese Industrial Standards (JIS) and American Iron and Steel Institute (AISI) use three digits to indicate different stainless steels, and are widely cited by the industry. Among them, the 200 series are chromium nickel manganese series austenitic stainless steels, the 300 series are chromium nickel austenitic stainless steels, and the 400 series chromium stainless steels (commonly known as stainless steels) include martensite and ferrite.

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 440

Application:

　　440C stainless steel balls are usually used in industries that require high precision and anti-rust performance such as aviation, aerospace, bearings, motors, high-precision instruments, valves, and petroleum.

Features:

　　The metallographic structure belongs to the martensitic steel, and the production process requirements are relatively high. There are relatively few domestic companies that can produce stainless steel 440C, so the companies that can produce 440C materials are often dubbed the reputation of special stainless steel. The heat treatment process is more complicated, easy to crack, and requires high precision. It is the hardest stainless steel ball among steel balls: HRC≧58. The hardness is close to the bearing steel ball, but it has stronger anti-rust and anti-corrosion performance than the former.

Comparison:

　　 Compared with 440 stainless steel ball, it has stronger anti-rust and anti-corrosion performance, the hardness is increased, and the wear resistance is also improved.

Established in 2006, Xi'an Machinery & Engineering Import & Export Co.,Ltd.（XMEC) is the successor to Shaanxi Marine and Engineering Import & Export Co., Ltd., which is specialized in importing & exporting mechanical and electrical products, complete equipment, various kinds of vessels and ships, marine equipment and port machinery, electronic and electric products, instruments and meters, minerals and metals, light industrial products, etc. XMEC also engages in different trading activities such as import and export of techniques and overseas project contracting.

With over 20 years of importing and exporting experience, we have good reputation from our customers at home and abroad, our source passed ISO9001:2008 and our products got SGS,RoHS Certificates etc.

Based on almost two decades of continuous efforts and development, our company has become one of the leading domestic facility which can supply high precision steel balls with complete specifications. We mainly produce Chrome steel ball (AISI52100, 100Cr6, GCr15, GCr15SiMn, SUJ2), Stainless steel ball (201, 304, 316, 420, 420C, 440C, 430), Carbon steel ball (1015, 1010, 1045, 1085), Tungsten carbide ball etc., Especially from 7.9375 mm - 82.55 mm high precision size chrome steel balls which are our principal products and used mostly for Wind Turbine Bearing, Slewing Ring Bearing and also the Bearing. The accuracy range of the steel balls we provide is from G10- G1000.

Based on customer’s requirement, the steel balls could be produced according to China Standard GB/T 308.1, International Standard ISO 3290, America Standard ANSI/ABMA Std. 10A, Germany Standard DIN 5401, Japan Standard JIS B 1501 etc.

With features of low-noisy, high-accuracy, best-service, our products have been widely used in various industry fields, such as aerospace industry, bearing, bicycle, auto industry, medical industry, electronic field, military industry, precision instrument and so on. They are all sold to overseas market with most competitive price and high quality.

We are looking forward to cooperation with you at the basis of mutual benefit in the near future.
