Comparison of Steel Material

in what application?

I am looking for strength. We make little tow bars and they are always getting bent.

Sounds like a poor design. SS will keep the bent parts from rusting.

Use thicker steel, or change the design.

I appreciate your response. But my question had to do with strength not corrosion. And the issue of design, yes are trying to redesign it. That is why the question of the better material. Do you work with material? Going to stainless is out of the question, for cost. A

Look at Mat web. Tensile strength may better you want flexural strength.

I'm on a phone and can't easily.

They have an excellent strength to weight ratio and are considerably stronger and harder than standard 1020 steel, but are not easily welded (need pre and post weld thermal treatment to avoid cold cracking).

Application is the question. 4130 is a very good choice for seamless tubing. Has been used in the aircraft industry for years. Strong and light weight. But, I might add it is used after much analysis has been completed (engineering) for the proper size and use.
