ASTM A36 is a common mild steel(carbon structure steel grade). It is widely used in morden industry owning to its cheapest rolling cost and easiest welding. S355JR and A283 Grade C steel, ASTM A36 mild steel is equivalent to grade Q235B under Chinese steel standard, grade S235JR under European steel standard EN 10025-2, grade SS400 in Japanese steel standard. These mild steel plates and sections are commonly bolted and riveted in structural applications.
Titanium microalloying is an element of S355JR and A283 Grade C steel strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in S355JR and A283 Grade C steel tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.
EN10025-6 S960QL structural steel plates are quenched and tempered high strength steel with yield strength of 590Mpa ~ 960MPa. S355JR and A283 Grade C steel, S960QL steel plates have technical requirement of flaw detection, Z15 Z35 thickness direction performance requirements, high strength and high toughness requirements and so on.
We have transportation department and shipping department to coordinate logistics and delivery. Seamless connection between inland transportation and sea transportation ensures smooth delivery, saves transportation time and delivers goods in the first time. During the sea transportation, we will update the freight progress for customers on a regular basis, so as to facilitate the tracking of customers and make preparations for receiving goods leisurely and timely.
