Introduction
Steel balls are divided into grinding steel balls, forged steel balls, and cast steel balls according to the production process. According to the processing material, it is divided into bearing steel balls, stainless steel balls, carbon steel balls, copper bearing steel balls and alloy balls. Among them, the bearing steel ball is an important basic component of the industry, and the alloy steel ball is a spherical shape formed by forging, spinning, rolling and casting with carbon, chromium, manganese, molybdenum and other metal elements as the main added metal elements. Shaped ferroalloy wear-resistant body, it is the most important part of today's crushing industrial mine ball and cement ball.From the perspective of application categories, steel balls can be divided into two categories: wear-resistant steel balls in the crushing industry and bearing steel balls in the precision bearing industry.
Bearing steel balls have a long history of use in the precision bearing industry and life, and they are more widely used. It can be said that most of the places where there is rotation, there are steel balls, commonly known as steel balls and balls. Steel ball is a general term for steel ball, steel segment and special-shaped grinding body. According to the appearance, it can be divided into a round ball (general narrowly defined name), capsule ball, elliptical ball, hollow ball, multi-faceted ball, multiple missing ball (with dimples on the surface), etc.
Metal balls are used mainly in precision ball bearing designs, roller applications and other demanding industrial applications. The surface is fine finished and hardened for a high load capacity.
A chrome steel ball demonstrates high hardness, resistance to deformation, and excellent wear characteristics. Chrome balls from us are manufactured from the highest quality chrome alloy electric furnace steel, and through-hardened for maximum strength and service life. Our strict production process assures highest dimensional accuracy and surface finish.
Before packing, the steel balls are sent to check the surface roughness, roundness, waviness, lot size variation and hardness according to specified control plans and procedures.
We mainly produce chrome steel with sizes ranging from 7.9375mm to 82.55mm. The main material is high chromium GCR15 or GCR15SiMn. Our balls are mainly used in the wind energy industry.Our products enjoy high evaluation and satisfaction among customers. Most importantly, we can customize products to meet the various needs of customers.
