Looking to buy EN19 Grade Steel Plate supplier for your Project? EN19 plate is a high quality Quenched and Tempered Alloy Structural steel. Good ductility is a result of high quality steel, high tensile strength and shock resisting properties in combination with resistance to wear. EN19 steel plate also known as AMERICAN SAE 4140 Plate. EN19 sheet is a high quality alloy steel with tensile strength. It is a high quality medium carbon. EN19 Steel plate is one steel grade in BS 970-1955 standard, which is specification for wrought steels for mechanical and allied engineering purpose.

With a combination of good ductility and shock resistance, EN-19 Plate is suitable for applications with very high loading such as engine gear boxes. SAE 4140 Plates are a popular material in the automotive sector it is possible to machine the material extremely accurately. EN 19 plate material is also in demad by Oil & Gas industry. 42CrMo4 Steel Plate is a prime choice because of its high strength. The SCM440 Plate equivalent grades are AISI 4140 sheet, DIN 1.7225/42crmo4 sheet.

AISI 4140 steel plate is an engineering alloy steel containing chromium and molybdenum. EN 19 Alloy Steel Plate comes under the class of low alloy steel. EN19 Plates have high fatigue strength, abrasion and impact resistance, toughness, and torsional strength. EN19 Alloy Steel Sheet can be heat treated in a number of ways to give it a combination of properties. Oil Quenched & Tempered Hardenss is 28-34 HRc. EN19 Sheets Annealing delivery hardenss is less than 250HB. EN19 sailhard steel plate has high tenile strength of 850- 1000 Mpa.

The EN19 steel plate equivalent grades are AISI 4140 plate, DIN 1.7225/42crmo4 plate.
