Titanium microalloying is an element of ASTM A387 Gr.11 plate for pressure vessels 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 ASTM A387 Gr.11 plate for pressure vessels 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.
Mechanical properties of S420NL-Z35 steel plate: yield strength≥235Mpa, tensile strength 360-510Mpa, elongation≥26%. The properties of ASTM A387 Gr.11 plate for pressure vessels, S420NL-Z35 steel plate determine its application. S420NL-Z35 steel plate has high strength and good welding performance, which is commonly used in the manufacturing of mining machinery, engineering machinery, coal mine hydraulic support and other equipment and structural parts.
Seamless steel pipe refers to the steel pipe made of a whole piece of metal without joints on the surface. According to the production method, it can be divided into hot rolling tube, cold rolling tube, cold drawing tube, ASTM A387 Gr.11 plate for pressure vessels, extrusion tube and spinning tube. According to the shape of the section, it can be divided into two types: circular and irregular. The seamless tube has a maximum diameter of 650 mm (expanding tube) and a minimum diameter of 0.3 mm (capillary tube), which can be divided into thick walled tube and thin walled tube according to the thickness.
