Applications of DIN 41Cr4 Steel
After quenched and tempered,1.7035 steel can be used in the manufacture of medium speed,the load of parts,such as machine tools gear,shaft,worm,etc. Atfer QT and high-frequency surface hardening,41Cr4 steel is always used in the manufacture of high surface hardness,abrasion resistance parts. After quenching and middle temperature tempering,this material is usually used in the manufacture of overloading,medium speed impact of parts.

 Quality Assurance
Below inspection will be done in the production.
(1) ray detection---RT;
(2) ultrasonic testing---UT;
(3) Magnetic Particle Testing-MT;
(4) penetration testing-PT; 
(5) eddy current flaw detection-ET
