High-nickel alloy steel strip with exceptional toughness and HRC 46–62 hardenability. The first choice for Damascus steel layering, ultra-wide bimetal band saw backing, and high-end knife making.
Get Quote for 15N20 View Specs ↓15N20 is a premium nickel-bearing steel originally developed by Böhler-Uddeholm. Its 2% nickel content delivers superior toughness, high hardenability up to HRC 61–62, and excellent etch contrast for Damascus steel patterns.
Available in widths up to 150 mm for ultra-wide band saw backing (6–12 inch blades). Precision heat-treated with ±0.5 HRC tolerance across full coil width.
The 2% nickel addition gives 15N20 its signature properties: deep hardenability, exceptional toughness, and resistance to ferric chloride etching that creates the bright layer in Damascus steel.
| C % | Ni % | Mn % | Si % | Cr % | Mo % |

15N20 offers a unique combination of properties that no other steel grade matches.
2% nickel refines grain structure and dramatically improves impact resistance. Blades flex without cracking even at high hardness.
Heat-treatable from HRC 46 (flexible backing) to HRC 62 (knife-edge hard). One grade, multiple applications.
Nickel resists ferric chloride etching, producing the bright contrast layer in Damascus billets. Forge welds cleanly with 1095 and SK85.
From industrial band saws to artisan knife making, 15N20 serves markets that demand premium performance.
Ultra-wide backing strips for 6–12 inch bimetal band saw blades. 15N20's toughness absorbs vibration while M42 or M51 teeth handle the cutting. Preferred for large timber and structural steel sawing.
The industry-standard bright layer in Damascus billets. Layer 15N20 with 1095 or SK85 for classic pattern contrast. Used by custom knife makers and Damascus billet producers worldwide.
Monosteel 15N20 knives at HRC 60–62 deliver exceptional edge retention with outstanding toughness. Popular for outdoor, bushcraft, and chef knives where blade durability is critical.
Both are nickel steels for band saw backing, but they serve different segments. 15N20 targets premium and ultra-wide applications; 75Ni8 is the standard for conventional bimetal backing.
Verdict: For conventional bimetal band saw backing, 75Ni8 is the cost-effective standard. For ultra-wide band saws, Damascus steel, or applications requiring HRC 55+, 15N20 is the premium choice.
