10 Carbon Steel Angles S235 Are Cold Drawn For Strength and Machinability

Cold drawn steel can reduce or eliminate the need for heat treating, handling and shipping, making it more cost effective.10 carbon steel cold drawing non The cold drawing process also makes the steel stronger, while enhancing machinability. Cold drawn steel is used in many different applications including bracing, support structures and frames, and reinforcement elements. It is often welded and can be used in general construction, marine and architectural applications. Cold drawn carbon steel angles S235 can also be used as a substitute for hot rolled or mild steel in construction projects that require a higher strength to weight application.

The cold-working of steel, which can be done either by cold rolling or cold drawing, improves both strength and hardness while reducing the percent elongation and reduction in cross section.10 carbon steel cold drawing non This makes cold-drawn steel easier to work, but it is not quite as good as wrought iron or other iron alloys.

When a bar is cold-drawn, it is pulled through a carbide die with high pressure and lubricants to reduce its cross-section without heating it.10 carbon steel cold drawing non This enables the bar to maintain its shape while being trued up and held to a very tight tolerance. It is then cleaned by shot blasting or acid pickling and may be resulfurized to promote better machinability.

Cold drawn bars have a bright finish that is workmanlike, but not polished. This is usually sufficient for most end-use applications, but if required, the material can be resulfurized to give it a softer, more machinable surface. This is particularly useful when the steel will be machined or turned to form a finished product.

The ASTM designations for structural steel are numbers that attempt to indicate the approximate alloy content of the steel, but it is not always very accurate. The first two digits in the number indicate the grade of the steel and the last one or two digits try to identify the type of alloying, such as zero for no alloying or 41 for chromium/molybdenum steel.

In addition to standard round bar, Precision Kidd offers a variety of cold drawn shapes, including squares, hexagons and octagons as well as flats/rectangles. These products are available in a full range of English and Metric sizes and can be surface improved to meet customer requirements for a more uniform surface quality and enhanced machinability.
