Product description
Details buyers use to confirm grade, use and supply.
420 Grade Stainless Steel Coating Wire
The 420 martensitic stainless steel grade offers a unique combination of properties in thermal spray coatings. Unlike austenitic grades like 304 or 316, the 420 alloy can be hardened through controlled cooling and post-spray treatments. This makes it an effective choice for rebuilding worn shafts, bearing seats, and other machine elements where a hard, durable surface is needed.
Typical coating characteristics include good frictional properties, moderate corrosion resistance (better than plain carbon steels but less than 316L), and a dense, machinable deposit. The 3.17 mm diameter is a standard size for high-deposition-rate arc spray systems and is also compatible with many wire flame spray guns.
Pack Options and Handling
We offer flexible packaging to suit different production scales and spray gun setups. Standard options include 15 kg, 20 kg, and 25 kg spools, as well as coil packs for larger volume jobs. Proper storage in a dry environment is essential to maintain wire surface condition and ensure consistent, smooth feeding through your spray system.
