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.
