The welding of EN steel grade S235JR plates

Our company has sales department, technology department, quality inspection department, after-sales department, logistics department. Each department has professional knowledge and high professional quality, put customers first, think about the interests of customers, actively communicate with customers and solve problems smoothly.

Q345B material is a low-carbon alloy steel (c <0.20%), with good overall performance, low temperature performance, cold stamping performance, welding performance and machinability. Q345R steel is a special plate for pressure vessels with a yield strength of 345MPa. It has good comprehensive mechanical properties and technological performance. In addition to the tensile strength and elongation requirements higher than Q345 (16Mn) steel, Q345R is also required to ensure impact toughness.

Manganese steel plates emerge as a profitable solution to diverse kinds of acid attacks. These have qualities surpassing an ordinary steel plate. Neither fully austenitic nor ferritic, these plates EN steel grade S235JR plates provide boosted resistance to chloride stress corrosion cracking, which the 300 series stainless steel plates are susceptible to. 22% Chromium allows these plates to withstand Sulphuric and Hydrochloric acid attacks, whereas Molybdenum (up to 3%) avoids crevice and pitting corrosion.

Titanium microalloying is an element of EN steel grade S235JR plates 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 EN steel grade S235JR plates 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.

The company adheres to the business philosophy of "good quality, customer first, honesty and trustworthiness", and strives to provide customers with high-quality EN steel grade S235JR plates products and excellent services.
