Our Chronifer M-17B  material is Manufactured in Rod, Bar and coil

AISI 440B ~ Stainless Steel

 

Material Properties

This steel is designed to provide stainless properties with excellent hardness.  In some respects it behaves similarly to tool steel.  Chronifer M 17B resists corrosion from mild atmospheres, fresh water steam, ammonia, many petroleum products and organic materials and several mild acid environments.

 

 

Availability

Coils: Cold drawn 10-35kg coil

Bars Ø 0-1.99mm: Cold drawn and polished

Bars Ø 2.00-40mm: Cold drawn, ground and polished

Bars Length : 2m or 3m. Surface roughness N5-N6

 

 

Standard Tolerances

Diameter: h7

Out of roundness/cylindricity :1/2 of dia tolerance

Tolerance in length : +50/-0mm

 

 

Corrosion Resistance

This grade is used in the hardened and tempered condition for a good corrosion resistance.  For optimum, corrosion resistance, surfaces must be free of scale and foreign particles.

 

 

Heat Treatment

Soft annealing: 750-800ºC

Slow furnace cooling (2-4 hours)

Hardening: 1000-1080ºC

Max obtainable hardness 57-59 HRC

 

 

Cutting Rate

20-35m/min (approx value, depending on the lubrication oil, the cutting tools, the shape of parts)

 

 

Stock Range

Standard dimensions from Ø 0.80 to 24.00mm with many intermediate dimensions.
