SS400 square tube is one of the most demanding but most commonly used structural steel available in hot rolled form.SS400 grade steel pipe, also known as JIS 3101 steel pipe, is a widely used low alloy carbon steel pipe. This type of steel grade is well known for its high tensile strength and offers excellent properties. The grade includes excellent properties and characteristics that make this grade even more demanding than other structural steel grades.
