What does Cold Cranking Amps (CCA) mean?

What does <b>Cold</b> Cranking Amps (CCA) mean?

This is the same test as the cold cranking amps test, except it is performed at 32°F (0°C). The cranking amps number will be higher than the CCA number, because of the warmer temperature, but you know what that means to a battery marketer- BIGGER IS BETTER!!!

If the plate is heavy, say 1/4" or so, cracking can be detered by grinding a small grove at each end of the piece only about a half inch or so. It should give the heel of the piece some relief when it is broke.

sp.info Steel material properties - SteelConstruction.info

For thin gauge steels for cold forming, no impact energy requirements are specified for material less than 6 mm thick. The selection of an appropriate sub-grade, to provide adequate toughness in design situations is given in BS EN 1993‑1‑10 and its associated UK NA. The rules relate the exposure temperature, stress level etc, to a 'limiting thickness' for each sub-grade of steel.

Brittle failure can result from such conditions and mild heating of the plate will reduce the tendency to failure. For similar reasons, forming should not be undertaken where the plate temperature is below 15°C. Formed plate components will generally exhibit springback on removal of the die or bending press force.

Why should you care about inside bend radii? - The Fabricator


Why <b>should you care about inside bend radii</b>? - <b>The Fabricator</b>

In cold-rolled mild steel, the minimum bend radius is 63 percent of the material thickness. For example, a piece of 12-gauge (0.104-in., 2.64-mm) material turns sharp at 0.065 in. (1.66 mm), making any punch radius less than that value, by definition, a sharp bend, such as 0.062 in. (1/16 in., 1.58 mm), 0.032 in. (1/32 in., 0.82 mm), or 0.015 in. (1/64 in., 0.38 mm).

sp.info How to prevent welding hot cracks? | LINKUN STEEL

According to the condition of crack formation, it can be divided into hot crack, cold crack, reheat crack and lamellar tear. As the name implies, the cracks generated at high temperature during welding are called hot cracks (thermal cracks/heat cracks), which are generated at high temperature close to the solid phase line and characterised by distribution along the grain boundary.

sp.info How To Weld 4140 Steel | WELDING ANSWERS

4140 will weld very similar to your low carbon steels. The difference is that its high carbon content can screw things up. To avoid cracking you need to preheat 4140 prior to welding. This is done to slow the cooling rate after we are done welding and avoid embrittlement, which can lead to cracking. Steps to weld 4140: 1. Preheat

sp.info 7018 question | Page 2 | MIG Welding Forum

The caveat being that we are ONLY talking about mild carbon steels, S275 structural strength. Once you go to stronger carbon or low alloy steels, the combination of metallurgy and higher strength means the amount of hydrogen in the weld and HAZ is really critical, and you might start getting cold cracking.

<b>Complying with NACE Hardness Requirements</b> - TWI

Although the cracking is described as stress cracking, the main problem is the hardness of the parent metal, weld metal and heat-affected zone (HAZ). NACE (formerly the National Association of Corrosion Engineers) has published two specifications that provide guidance on reducing the risk of in-service cracking, these also being ISO standards.
