Product Description
95Cr18 High Hardness Martensitic Stainless Steel Round Bar 440A 440B 440C for Bearing and Wear-resistant Parts
Product Overview
95Cr18 high hardness martensitic stainless steel round bar is available in 440A, 440B, and 440C grades, specifically engineered for bearing components and wear-resistant parts. This material combines exceptional hardness with good corrosion resistance, making it a reliable choice for demanding industrial applications.
95Cr18 440A 440B 440C Martensitic Stainless Steel Round Bar
Key Characteristics
- High Hardness: Achieves excellent hardness levels after heat treatment, suitable for high-wear environments.
- Martensitic Structure: Provides superior strength and wear resistance compared to austenitic or ferritic stainless steels.
- Corrosion Resistance: Offers moderate corrosion resistance, ideal for applications where both hardness and some level of rust protection are required.
- Versatile Grades: Available in 440A, 440B, and 440C to match specific hardness and toughness requirements.
- Round Bar Form: Precision round bar stock ready for machining into bearings, shafts, valves, and other wear-resistant components.
Typical Applications
- Bearing races, balls, and rollers
- Wear-resistant parts for pumps and valves
- Cutting tools and blades requiring high edge retention
- Precision shafts and spindles
- Industrial machinery components subject to abrasion
Grade Comparison
| Grade | Carbon Content | Hardness (HRC) | Key Features |
|---|---|---|---|
| 440A | ~0.60% | 54–58 | Good corrosion resistance, moderate wear resistance |
| 440B | ~0.75% | 56–60 | Higher hardness and wear resistance than 440A |
| 440C | ~1.00% | 58–62 | Highest hardness and wear resistance in the 440 series |
Hardness values are typical after appropriate heat treatment. Actual results may vary based on processing conditions and component geometry.
