  • Advantages of NM360 wear-resistant steel plate: NM360 steel has high strength: generally its yield strength is above 300MPa. 2. High toughness: The elongation is required to be 15% -20%, and the room temperature impact toughness is greater than 600kJ \/ m ~ 800kJ \/ m. For large welded components, high fracture toughness is also required. 3. NM360 steel plate has good welding performance and cold forming performance. 4. Low cold and brittle transition temperature.

What is Free Machining? - Definition from Corrosionpedia

Free machining pertains to the machining characteristics of an alloy to which one or more ingredients have been introduced. Alloy M25 (beryllium alloy of copper), for example, is a free machining type of copper. Commonly added elements for free machining materials are: Sulfur or lead to steel; Lead to brass; Lead and bismuth to aluminum What does "free-machining" mean regarding 303 stainless? 303 machines like ordinary construction steel which means = excellent ! I used 1mm Osawa endmill for making small details from 20mm 303 rod, details were similar to hard couplings (small protruding teeth on face). I made the cut in 10 layers and each detail took about 50 minutes of machining time. Dry milling, constant air blow for chip removal.
