Keystock Revisted

Or, “Keystock, we hardly knew ye. . .” So, back in April of last year I was eulogizing Keystock; at least the longer length, higher strength, plus-tolerance kind, that for years had been a “go-to” product for a lot of people. It seemed Keystock would be going the way of the Dodo bird. But, I was apparently wrong. More correctly, it was going the way of Coke, or New Coke, or Original Coke, whatever. The […]

Lean Duplex – Part Two: Who Can Use This Product?

The easier question to answer would be; who can’t use it? A continuation of last month’s post: Service temperatures should not exceed 750F. Any customer currently using stainless of the following types: 304L, 316L, 410, 416, 17-4ph should consider LDX, (ASSOCIATED STEEL’S ASC2250 LDX). LDX is now made by several steel mills, to their own specific variances. In general, it is a great stainless grade for heavy maintenance applications where the grades listed immediately above […]

Lean Duplex Stainless: What Is It?

If memory serves, I did a post on Lean Duplex some time ago. It is an important grade of stainless and worth a revisit. Basically, Lean Duplex is a leaner chemistry derivative of Duplex Stainless Steel. Duplex Stainless Steel is recognized as having a unique shared grain structure; Austenite and Ferrite. Each of those grain types contributes to the characteristics and performance of the steel grade. The grade was developed to provide resistance to Stress […]

About Chromed Rods Part Three of Three

This is the last of our three-part post on chromed shafts. In order to extend service life, by resisting surface wear on the rod, the rod surface needs to be hard. It also needs to be relatively smooth, so as not to tear up the seals. And the rod needs to be straight. In most cases, chrome is an ideal surface coat for Hydraulic Rods. Hard Chrome may be better. IHCP is better still. The […]

About Chromed Rods – Part Two of Three

Continuing from our last post, we are discussing chromed rods. When they are applied correctly, chromed Rods typically extend service life compared to standard carbon and alloy bars. Variables relative to those materials would be the steel type, actual hardness, and the type of hardness (surface or throughout). The benefits of chromed rods address sliding surface abrasion and corrosion. In actual service, however, even sliding abrasion applications are not just limited to sliding abrasion. Small […]

How to Order Steel: Make it Easy for Everyone

You do not have to be a metallurgist or engineer to accurately order steel. But you don’t want to order steel plates and end up with dishes. Take some time to ensure your language will be understood by the vendor. I’m not speaking about dialects, but try to avoid esoteric terms that may just be what you use at your company. Avoid jargon. Take a moment to familiarize yourself with the terms the vendor uses. […]

About Chrome Rods

Part one of three – I thought we would sneak into 2021 by looking at a steel shaft that is often misunderstood; Chromed Steel Shafts (Rods). Chromed steel shafts are referred to as “Rods”, or “Cylinder Rods”. Not all are used for Cylinder applications. The manufacturing and automation industry is a prolific user of this type of product. The default term Rod, is simply “jargon of the trade”. The base metal may be mild steel […]

Clad Wear Plate – “Overlay” Plate; What is it?

The term “wear plate” doesn’t give you much by way of steel specification. Nor do the terms “Overlay Plate or Clad-Plate” Wear Plate, Abrasion Resistant (AR) plate, is primarily used in heavy industrial maintenance applications. (Note that “AR” may also refer to As Rolled plate, but that is not the context we are using here). If a job is banging, clanging, screeching, or in any way loud and offensive it most likely is tearing up […]

Bending Steel for Novices

Recently, I thought I’d check the internet to see what was posted relative to bending steel. It is a very broad subject, like asking “What is the price of a car?” Very difficult to answer without lots of clarification, clarification not only relative to the nature of the steel, the hardness, the bend, the bend radius, the equipment, the operator, and so on. Will you be cold bending, or applying heat? Quickly run through the […]
