Our Chronifer M-17B is a high carbon chromium steel which is manufactured in rod, bar and coil. (AISI 440B ~ Stainless Steel). For all stock and size availability contact Sales.

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.
