Stainless Steel Guide Pin

Stainless steel guide pin parts come in a bunch of standard sizes,diameters from like 3mm up to 40mm and bigger, different lengths, head styles (like shouldered, headed, or flanged), and tip shapes (chamfered, rounded, or flat). These follow the specs you’d find in catalogs from major industrial suppliers. The tolerances are tight (usually h6 or h7) to make sure they fit perfectly in the matching guide bushings. That’s key for keeping the alignment spot-on every time in tooling setups.

Enhanced corrosion resistance

Stainless steel guide pin is pretty corrosion-resistant on its own, but there are ways to make it even better. Passivation is a common step,this process removes any free iron and helps build up that protective chromium oxide layer, which really amps up rust resistance. For jobs where they’ll take a ton of wear, they might add a hard chrome coating over the hardened stainless steel base.

There are other coating options too, like DLC (that’s Diamond-Like Carbon) or nitriding. These give ultra-low friction and super high surface hardness. The choice comes down to what you need beyond the basic properties,like how much wear they’ll face, how corrosive the environment is, or if you need a non-stick surface. Basically, it’s about tailoring the finish to the specific job requirements.

Provide Certified Material Test Report (CMTRs)

We give full test certificates for every batch of stainless steel guide pin. These papers check the exact chemical makeup,like Chromium is usually 11.5-13.5%, Carbon around 0.15%, stuff like that, which varies a bit by grade. This makes sure the material meets standards like ASTM A582. Having this info means you can track where the steel came from and be sure it has the properties it’s supposed to. Basically, the certificates prove the stainless steel pins are the real deal and meet specs.
