BSS stock a range of annealed spring steels – including grade CS70 and grade 75Cr1. And it will spring back. Quite normal for spring steel, isn't it.

You can bend it. Start the same way and make a few turns of an expansion spring (wire touching itself). I also tried annealing with a band-blade welder, which really didn't work--it just made the steel …

Annealing is a process that is undertaken after the rolling of steel to soften the steel and make it more malleable to facilitate forming. The American Iron and Steel Institute specification number 1070 works well.

Edit. But due to the hardening it remain its form. Spring steel is a name given to a wide range of steels used in the manufacture of springs, … Carbon spring steels are also available in the annealed condition. I've tried bending it as is--it just snapped. This page shows summary ranges across both of them.

This piece of steel works not only as a visual guide, but also as a physical barrier against the angle grinder's disc, preventing you from cutting too little or too much by mistake. Classic editor History Talk (0) Share. Spring steel is hardened carbon steel, not so special. This piece of steel works not only as a visual guide, but also as a physical barrier against the angle grinder's disc, preventing you from cutting too little or too much by mistake. These steels are generally low-alloy manganese, medium-carbon steel or high-carbon steel with a very high yield strength.This allows objects made of spring steel to return to their original shape despite significant deflection or twisting. Spring steel is a plain carbon steel with a carbon content of around .7%.

In stock and ready to ship.


Compression springs are ones that squish, like the spring in a ballpoint click pen. The properties of ASTM A227 spring steel include two common variations. Classic editor History Talk (0) Share. Introduction: Tempering is a type of heat treatment for iron-carbon alloys. Make the guide from relatively thick (3mm+) steel to ensure you don't cut through the guide itself by mistake. I want to form or bend it in several locations to make the shape I want. Edit. These alloys are more formally called steel. Still another variation of coiled springs is the watch spring, which is coiled into a flat spiral rather than a cylinder or cone. Just make sure that the strip is thin enough to bend.


The holes drilled in Step 1 allow the ends to be secured to almost anything. Idahoan Dean Williams used to make a living by repairing vintage mechanical cameras.

Make the guide from relatively thick (3mm+) steel to ensure you don't cut through the guide itself by mistake.
