Sheffield has always been at the heart of UK steel and engineering. The city's precision engineering and sub-contract machining sector is one of the most active in the country — from aerospace and defence sub-suppliers to automotive Tier 1 and Tier 2 components, cutting tools, and specialist machinery manufacture.
We stock the alloy grades that Sheffield engineers rely on: EN19 (42CrMo4/4140) for high-tensile shafts and gears, EN24T (817M40T/4340) for aerospace and defence components, EN36 and 8620 for case hardened gearing, and EN40B for nitrided precision shafts. Large-diameter black round bar to 600mm — one of the widest ranges available from a single UK stockholder.
