Special features and main characteristics: rust-resistant, hardenable chrome steel, whose corrosion resistance is achieved only through the hardening of the parts. To further improve this, the parts must be well polished. Due to its low sulfur and carbon content, this grade is more corrosion-resistant than 1.4034 or 1.4035. However, the hardness is lower than 1.4028 or 1.4034. The use of this material is versatile, covering applications in industries such as medicine or dental for undemanding parts.

Brief description
Designation Klein:
CHRONIFER M-4021
Class of metals:
Hardenable martensitic stainless steel
Material number:
1.4021
Standard EN:
X 20 Cr 13
Machinability:
satisfactory
Hardening capability:
up to 45 HRc
Polishing ability:
adapted for mirror polishing
Corrosion resistance:
satisfactory in the hardened, polished
and passivized condition
Magnetism:
magnetic
Uses:
medical, surgical and dental
instruments
Special features and main characteristics: rust-resistant, hardenable chrome steel, whose corrosion resistance is achieved only through the hardening of the parts. To further improve this, the parts must be well polished. Due to its low sulfur and carbon content, this grade is more corrosion-resistant than 1.4034 or 1.4035. However, the hardness is lower than 1.4028 or 1.4034. The use of this material is versatile, covering applications in industries such as medicine or dental for undemanding parts.
