METALS · ALLOY STEEL
Alloy steels are the engineering grades — 4140, EN19, EN24 and their equivalents — machined into shafts, gears, pins and tooling. Workshops rarely need a full bar; the short lengths and plate off-cuts listed here match how this material is actually used.
Stock turns over piece by piece — what's listed is what exists. Post the spec you need and we match it against incoming material; you're alerted the moment something lands.
4140 (42CrMo4 in European naming) and EN19 are near-equivalents and cover most shaft and stud work; EN24 steps up where toughness matters. These grades respond to heat treatment, which is the point: a machine shop turns a blank, then hardens and tempers to the duty.
Condition matters when you buy: quenched-and-tempered bar machines differently from annealed. Listings state the declared condition where the seller provided it, and pieces with a mill certificate carry the MTC badge so you can match the chemistry to your spec before ordering.
Common grades in this family: 4140 · 42CrMo4 · EN19 · EN24 · EN8
Close enough that they interchange in most workshop use — both are chromium-molybdenum medium-carbon steels with similar heat-treat response. Check the certificate when the drawing calls a specific spec.
Whatever the seller declared — usually quenched and tempered, sometimes annealed. The condition is on the listing, and the mill certificate confirms it where one exists.
That is exactly what this stock is for. Off-cut lengths are listed piece by piece with the actual dimensions, so a 400 mm job doesn't require a 6-metre bar.
