Alloy 440B Stainless Steel is a high carbon chromium steel which 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
- Bars Ø5-50mm: Cold drawn and polished
- Bars Ø 10.00-350mm: Cold drawn, ground and polished
- Bars Length : 2m- 6m. Surface roughness N5-N6
Standard Tolerances
- Diameter: 5-350mm
- 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.
TYPICAL APPLICATIONS
Commercial applications for this engineering material include:
- Valve seats
- Cutting tools and knife blades
- Bearings
- Surgical instruments
