What Is Stainless Steel 2Cr13?

2Cr13 steel is a kind of martensitic stainless steel. Its carbon content is about 0.16-0.25 percent and chromium content is around 12-14 percent. It has high hardness and good rust resistance, and is widely used for cutting tools, medical devices, valves and molds.

2Cr13 Stainless Steel Equivalent — DIN

Grade:

DIN 1.4021 / X20Cr13

Performance:

The hardmess is 28-34 HRC. It adopts stable German craftsmanship with minimum deformation after heat treatment, suitable for precision measuring tools and mold inserts.

Chemical Composition:

C: 0.18-0.22%

 

Si: ≤1.00%

 

Mn: ≤1.00%

 

P: ≤0.045%

 

S: ≤0.030%

2Cr13 Stainless Steel Equivalent — Japan JIS

Grade:

JIS SUS420J1

 

Performance:

Hardness reaches 28-34 HRC in quenched and tempered condition. Japanese steel mills adopt stricter purity control, delivering a finer and brighter surface after polishing.
 

Chemical Composition:

C: 0.16-0.25%

 

Si: ≤1.00%

 

Mn: ≤1.00%

 

P: ≤0.040%

 

S: ≤0.030%

 

Cr: 12.0-14.0%

2Cr13 Stainless Steel Equivalent — China GB

Grade:

GB 2Cr13
 
 

Performance:

The hardness of 2Cr13 stainless steel is no more than 223 HB (roughly ≤22 HRC) in the annealed state for easy machining. It reaches 28-34 HRC after quenching and high-temperature tempering with good overall performance and high wear resistance. As a 2cr13 stainless steel equivalent, its biggest advantage is the highest cost performance.
 

Chemical Composition:

C: 0.16-0.25%

 

Si: ≤1.00%

 

Mn: ≤1.00%

 

P: ≤0.030%

 

S: ≤0.030%

 

Cr: 12.0-14.0%

2Cr13 Stainless Steel Equivalent — UK BS

Performance:

Hardness is 28-34 HRC after quenching and tempering. This British standard steel has strict impurity control with low phosphorus and sulfur. It owns high purity, stable quality and reliable overall performance. It is a traditional European industrial standard steel.
 

Chemical Composition:

C: 0.16-0.25%

 

Si: ≤1.00%

 

Mn: ≤1.00%

 

P: ≤0.040%

 

S: ≤0.030%

 

Cr: 12.0-14.0%

 
 

Conclusion

Six scenarios, six options:

 
  • Tight budget, large quantity and low surface requirements → Choose Chinese 2Cr13.
  • Heavy turning and drilling work → Choose AISI 420.
  • Medical surgical tools and mirror polished parts → Choose JIS SUS420J1.
  • Precision size parts with no further machining after heat treatment → Choose DIN 1.4021.
  • Export to the EU with ISO standard required by clients → Choose X20Cr13.
  • Export to the UK or BS standard required by customers → Choose British 420S21.
