High Strength Steel Structural Washers

Surface treatments make high strength steel structural washers used in high-strength steel structures work better and last longer. Methods like electroplating with zinc or nickel help prevent rust and can improve their appearance. Hot-dip galvanizing adds a thick protective layer, which is great for outdoor use where they might get wet or exposed to the elements.

Phosphating is another treatment that helps the high strength steel structural washers hold onto oil, reducing friction in parts that move fast, like in engines or machinery. For stainless steel washers, passivation removes tiny iron particles that could cause rust, making them more rust-resistant. Powder coating adds color (which helps with labeling or sorting) and protects against chemicals. Black oxide finishes are used in sensitive equipment because they cut down on light reflection, which is important for things like cameras or precision tools.

Even non-metal washers get treatments,UV-resistant coatings keep plastic or nylon ones from breaking down in the sun. All these treatments ensure plain washers can handle moisture, chemicals, and temperature changes, so they’re good for tough environments like marine (saltwater), chemical plants, or cars.

Size

High strength steel structural washers follow standard sizes (like ISO 7089 or ASME B18.22.1) so they work worldwide. The main measurements are inner diameter (ID), outer diameter (OD), and thickness. Sizes go from tiny M1 (1mm hole) for microelectronics up to huge M100+ for big industrial machines.

The OD matters for how much load they can spread.Bigger washers are better for soft materials like wood or plastic because they distribute pressure over a larger area. Thickness affects how much they can compress: thicker washers handle more pressure, while thin ones are for lighter jobs. If you have a unique bolt or a non-standard use, you can get custom sizes made.

There are metric and imperial options to fit different regions,Europe uses metric, the US might use imperial, for example. Manufacturers give clear charts to help you match washers to the right screws or bolts, so you don’t end up with parts that don’t fit and cause problems.

Withstand extreme temperatures or harsh chemicals?

The bearing capacity of high strength steel structural washers under different conditions depends on the selected material and coating. Stainless steel washers can withstand high temperatures up to 800°C and are resistant to acids and alkalis. Stainless steel can be used in chemical environments. Nylon washers are okay for temps up to 120°C, but strong solvents will make them break down over time.

If you need stronger chemical resistance, try hot-dipped galvanized washers (they’ve got a thicker rust-proof layer) or PTFE-coated ones (their slick surface handles most chemicals). For freezing temps(like sub-zero spots),austenitic stainless steel works best because it doesn’t get brittle when it’s cold.

Just give us details about where the high strength steel structural washers will be used: temperature swings, exposure to water, chemicals, or rough conditions. This helps you choose the right combo of material and coating to avoid early wear and tear.
