EN S355JR DIN ST52 GB/T Q345B Carbon Structural Steel Bar / Rod
INTRODUCTION
Low alloy high strength structural steel is made by adding a small
amount of alloy elements on the basis of carbon structural steel
(Wc=0.16%~0.2%). It has good weld ability, plasticity, toughness, processing technology, better corrosion resistance, higher strength
and lower critical transition temperature of cold brittleness. Their grades are basically the same expression as those of carbon structural steel. It is suitable for manufacturing large
steel structures of railway, high pressure vessel boilers, automotive tractors and large
military engineering.
APPLICATIONS
It has a wide range of uses and a large amount of usage. It is
mainly used in railway, bridge, all kinds of construction projects,and to produce all kinds of
metal components bearing static loads, mechanical parts and welding
parts which are less important and need no heat treatment.
