Description
5KhNM tool steel grade and application notes
The technical record describes 5KhNM for large hammer and press dies, inserts and other hot-forming tools exposed to impact and thermal loading. State the exact grade spelling, governing specification, delivery and heat-treatment condition, dimensions, tolerances and certification requirements with the inquiry.
5KHNM steel is used: for the manufacture of forgings parts, General engineering; hammer stamps vapor and pneumatic hammers weight of falling parts over 3 tons; press tools and dies high-speed stamping machine for hot deforming of light non-ferrous alloys; blocks of matrices for inserts of horizontal forging machines; solid-rolled rings for different purposes.
Note
In the manufacture of forgings from ingots weighing more than 21 tons casting steel must be made in a vacuum.
