 ● Features and application: 
 9Cr18Mo is the production of bearing rings and rolling with a high carbon chromium stainless steel. Cutting and slicing machines for stainless steel cutting tools, surgical blades, high wear-resistant equipment, spare parts. 9Cr18 martensitic stainless high carbon chromium bearing steel. After quenching with high hardness and wear resistance, high temperature, low temperature dimensional stability. 9Cr18Mo features and use the same basic and 9Cr18 steel, but has a higher hardness after quenching and tempering resistance stability of the passivation of stainless steel to increase the role of molybdenum. 9Cr18, 9Cr18Mo carbon chromium stainless steel ball Applications: suitable for manufacture in the sea water, river water, nitric acid, steam, and marine and other corrosive media bearing, such as ships, submersible pump components of bearings, oil and chemical machinery bearings, marine instrument bearings.

 Chinese grade is expressed as: 
 According to GB / T "grade steel products, said method" requirement, the use of phonetic alphabet, Arabic numerals and symbols of chemical elements in the way in combination. 
 Content: in general the head grade Arabic numerals with an average carbon content (in parts per thousand dollars); average carbon content of less than one-thousandth of the use of "0"; carbon content of not more than 0.03% with "00" means. 
 Alloying element content: an average of less than 1.50% content of alloying elements, the grade, only marked elements, generally do not indicate the content; content of alloying elements on average 1.5% -2.49% 2.50% -3.49 22.50% -23.49 %..... %,...., the corresponding labeled 2,3 ..... 13 .... 
 Special purpose stainless steel, in the grade of steel use on behalf of the head with the code. 
 For example: 0Cr18Ni9, Y1Cr17 (cutting steel).
