ASTM A514 Gr. B Steel need specs of this grade
ASTM A514 Gr. B Steel need specs of this grade
(OP)
I've got a customer who specifies ASTM 514 Gr. B steel for the manufacture of a centrifugal fan rotor (8' diam) with thicknesses of 3/4" to 1/4" for a cement plant, welding should be by AWS 11018 rods and some parts requiere a complicated doble bend that will have to be done by spinning the material in a lathe (compound curve lips).
Question: What is the alloy specs for this steel y can only get it for the ASTM 517 with no grade specification from a local supplier (Bohler-Austria Chronit T-1 in grades 400 and 500 they can't specify the denominational diference between both types, they are 400BHN and 500 BHN)
Has any one any experience spinning this material (1/4" thickness and 5' diam for the inlet mouth)
Any suggestions will be welcomed
Thanks

The basic differences can be viewedby looking up the spec here http://w
The types/grades corresppond in many cases if not all. You can look up the uns number here http://

This document, from a previous post, shows properties and uses for a number of different steels- I'm not sure if it includes yours.

I have used ASTM 514 in the past. It is excellent material. Be careful if you are welding. Not all welders and welding process are appropriate for A514. I love to make high strength mechanical part of it (a hinge for example) and I do that by machining. It machines real well.
ASTM A 514 and A 517 are specifications for high-strength quenched and tempered plate for structural and pressure vessel applications; A 514 type A has the identical composition limits as A 517 grade.
United States Steel was first to introduce this fine material under their proprietary name T-1 steel. Due to the proprietary nature, the alloy composition of the material could not be divulged. Therefore, the industry introduced the ASTM A 514 as equivalent to T-1 steel.
There are several grades for A514. Each grade has separate mechanical properties. I can fax you some properties for the various grades of A 514 from my machine handbook.
