S355 – an useful structural grade steel with a minimum yield strength of 355 N/mm².
S355 being widely used in the structural engineering and important source construction industries, S355 offers high yield and tensile strength and is supplied with a variety of treatments and test options to ensure that it is a highly usable steel in your various projects.
S355 structural grade (S) carries minimum yield strength of 355 N/mm²m, the JR designation confirms that the link for you steel has undergone longitudinal Chary V-Notch impact testing at 27J (Joules) at room temperature. Other Charpy designations include J0, J2 and K2.
S symbol for Structural Steel
JR symbol 20 temperature impact test
J0 syambol 0 temperature impact test
J2 symbol -20 temperature impact test
S355JR Application
Suitable for wide variety of structural application for instance: freight cars, transmission towers, dump trucks, cranes, trailers, bull dozers, excavators, forestry machines, railway wagons, dolphins, penstocks, pipes, highway bridges, building structures, offshore structures, shipbuilding, fans, pumps, lifting equipments and port equipments.
