Steel is one of the most popular metals that are used today, especially stainless steel. Stainless steel is an alloy that is composed of iron and other elements, with carbon having the usual content of .The other elements in stainless steel are vanadium, tungsten, manganese, and chromium. Learning more about the different properties of steel would teach you more about how why steel has become more popular these days.Tensile StrengthThis is the ability of steel to withstand the stretching done to the material. This property can be measured by getting the cross section of steel and dividing it by the stress exerted on the area of the material.

The tensile strength of steel is 40,000 pounds of force per square inch or 40 KSI. Moreover, steels compressive strength is also similar to its tensile strength. This is evident in the way that steel responds equally to both stretching and crushing forces.ElasticityThis is the ability of steel to resume its normal shape even after being hit with an external force that has been removed then. Only elastic solids will not get deformed or break after being put to test with a certain amount of external force. This can be calculated using the formula of tensile stress or tensile strain. Steels elasticity is 30 x 106 psi.HardnessThis is the property of steel that makes it resistant to forces such as penetration, deformation, machining, scratching, abrasion, and yielding. This is usually tested using the tests by Brinell, Rockwell and Vickers. The testing is done with the use of an indentor that is placed on top of the material being tested.

A certain load is then placed on top of the indentor. After the test, the indentation size will be measured which can give the hardness of a material.ToughnessThis is the property of any alloy to absorb energy and get deformed physically. The factors that affect the China Braze Tube Union Company toughness of a material are temperature, rate of loading or strain, and notch effect or the distribution of stress. Toughness is directly proportional to temperature change and inversely proportional to the rate of loading.Ductility and MalleabilityThese are properties that measure the application and utility of steel. Malleability determines the ability of an alloy to compress without cracking. Ductility measures the extent of how an alloy can stretch itself without enduring some fractures.

These two properties can help determine if an alloy material is ideal for rolling or forging purposes.Specific Properties of Stainless SteelStainless steel contains steel, iron, and at least 11% of chromium content. Chromium is the element that makes stainless steel resistant to corrosion. Based on the properties of stainless steel, there are four types of this alloy material. These are martensitic, ferritic, ferritic-martensitic, austenitic, and ferritic-austenitic.Stainless steel can be subjected to testing using temperature variation and rapid loading. Austenitic steel is tested to have excellent toughness whatever the temperature it is subjected to. Stainless steel also has yield strength that is the property of an alloy to endure maximum stress without causing plastic deformation.
