EN19 SCM440 Tube supplier
EN19 is referred to by most manufacturers as a kind of Engineering Steel. This particular steel grade is known to have a high tensile strength along with good ductility as well as shock resistance. Attractive qualities like these make the EN19 Seamless Tube one of the most sought after products available across the markets. Apart from being used in the automotive industry, the oil and natural gas industries benefit from using the En 19 piping material as well. Moreover, this material offers good wear resistance in addition to being easily case hardened. The material is able to exhibit excellent performance, especially in those applications where higher tensile strength is a principle property requirement. This high quality structural steel is a Quenched and Tempered Alloy grade. Essentially a medium carbon steel grade, once oil tempered and quenched, the hardness of this EN19 Alloy Steel pipe ranges between 28 - 34 HRC & in an annealed condition, its hardness is lesser than 250HB.
EN19 SCM440 Pipe is a medium carbon alloy steel, whose chemistry includes elements such as chromium & molybdenum. The advantage of using SCM440 grade EN19 Seamless Pipe is its stable composition, high steel purity, few surface defects, as well as low harmful elements, and small decarburization layer. In a quenched and tempered condition, the 42CrMo4 EN 19 Alloy Steel Pipe exhibits a good aggregate of properties like strength and toughness, making it useful, particularly in the oil industry.
