Metal Grade Carbon Steel Grades Chart

The most popular metals here are the most common carbon steel grades in chart form. A similar japanese specification sets carbon between 47 53 and allows for silicon and other trace elements whereas the astm standard does not.

Metal grade carbon steel grades chart. If you don t want to put a lot of effort into your material picking stick with these common types of tubular steel your steel tube manufacturer will know all about them. For example the astm 1050 grade steel is so named because it is approximately 50 carbon by weight. The sae j403 grade 1010 specification states that the steel may be supplied with carbon content from 0 08 to 0 13 percent.

Read part 2 to learn more about. The table below shows the complete designation system. It is affordable while still providing excellent mechanical properties.

On the other hand in the case of sae j403 grade 1008 the spec allows for up to 0 10 percent carbon with no minimum. Carbon steel is typically composed of 0 05 to about 2 0 carbon measured by weight along with iron and trace amounts of other elements. For example a nickel steel with about 3 nickel and 40 carbon is represented by the metal number 2340.

However the tolerance for carbon percentage in the astm 1050 standard is 48 55. Astm s steel standards are instrumental in classifying evaluating and specifying the material chemical mechanical and metallurgical properties of the different types of steels which are primarily used in the production of mechanical components industrial parts and construction elements as well as other accessories related to them. For alloys in general including steel unified numbering system uns of astm international and the society of automotive engineers sae.

Once heat treated it becomes extremely hard and brittle. High carbon steel is very difficult to cut bend and weld. Carbon steel is commonly used across many industries.

Carbon steels and alloy steels are designated a four digit number whereby the first digit indicates the main alloying element s the second digit indicates tg top grade element s and the last two digits indicate the amount of carbon in hundredths of a percent basis points by weight for example a 1060 steel is a plain carbon steel containing 0 60 wt c. Steel grades standards by country. Japanese steel grades.

European standards en 10027. Carbon steel grades chart pdf. According to the world steel association there are over 3 500 different grades of steel encompassing unique physical chemical and environmental properties.

This article is the first of a four part series on the different types of steel. Since it is a very common selection for a variety of purposes it is important to know how to choose the right carbon steel grade. Commonly known as carbon tool steel it typically has a carbon range between 0 61 and 1 50.

American steel grades. For example 1010 steel is a carbon steel with a nominal 0 10 percent carbon level. Aisi sae steel grades standard british standards.

In essence steel is composed of iron and carbon although it is the amount of carbon as well as the level of impurities and additional alloying elements that determine the properties. The system designates the approximate steel carbon range the manufacturing process used to produce the steel and the major elements in steel.
