With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
Q235 steel has good plasticity, toughness and weldability, as well as a certain strength, good cold bending performance. Q235 material is usually rolled into wire rod or round steel, square steel, flat steel, angle steel, I beam, channel steel, other sections and steel plates.
Q235 steel plate equivalent steel standard-astm a36. If only from mechanical properties of materials, it is acknowledged that mechanical properties of A36 and SS400 are similar to those of high quality carbon structural steel 20#. Tensile strength of 20# steel is not less than 410; yield strength is not less than 245; mechanical properties of SS400 and A36 are about the same.

These comparison table is only intended as an indication of the closest khown equivalent grades.
Q235 carbon steel contains four different grades as Q235A,Q235B,Q235C and Q235D.The big difference among these four carbon steel grades is the impacting temperature.
When the general strength design is presented, Q345 is used because Q345 is not only strengthened than Q235 but also save 15% to 20% steel compared to Q235 steel. However, for stability control design, Q235 steel is better. The price difference is 3%- 8%. Regarding how to distinguish the steel plate from Q235 and Q345, therere several methods:
Q235A Included in 3 standards (China) Elongation: > 24 % Thickness: 100 - 150 mm ; Yield Strength: > 195 MPa Tensile Strength: 370 - 500 MPa Elongation: > 22 % Thickness: 150 - 200 mm ; Yield Strength: > 185 MPa Tensile Strength: 370 - 500 MPa Elongation: > 21 % Cold-bend test Longitudial test pieces Thickness: < 60 mm ; Return Bend: d=a Thickness: 60 - 100 mm ;
Boiling steel is inferior steel deoxidation incomplete, ductility and toughness. Welded structure of this material, when the joint is prone to crack under dynamic loads. Should not work at low temperatures, sometimes produce hardening. In contrast, high quality and uniform killed steel, ductility and toughness are good. Q235 Mechanical behavior:
Hello, Q235 steel is a Chinese carbon structural steel, Yield Strength is 235 MPa, Tensile Strength is 370-500 Mpa. You can find more info here: Q235 Steel Chemical Composition, Mechanical Properties & Equivalent.
The above is the brief introduction of the advantages of expansion joints. The advantages include easy installation, force compensation, size adjustment and others. If you want to know more about it, please contact with us. Threaded Connection Rubber Expansion Joint
Tensile Strength. While there is no large difference when it comes to tensile strength, ductile iron has the greater yield strength (40 ksi). Cast steel, on the other hand, can only reach 36 ksi yield strength. Ductile Iron (ASTM A536) vs Cast Steel (ASTM A27) As the strength of ductile iron increases ductility decreases.
Q195, Q215, Q235, Q255 and Q275 in the material What is the difference? Carbon steel structural steel is the most widely used, the maximum number of, often rolled into steel, shapes and sections, generally does not require the use of direct heat treated, mainly for construction and general engineering.
Q235B mild steel round bar and flat sections can be cut to your required sizes. Q235B low carbon steel grind bar can also be supplied, providing a good quality steel precision ground tool steel bar to your required tolerances. Q235B steel is also available as Grind Flat Stock / Gauge Plate, in standard and nonstandard sizes.
And whether steel plate q235a is container plate, ship plate, or flange plate. There are 1,394 steel plate q235a suppliers, mainly located in Asia. The top supplying country or region is China, which supply 100% of steel plate q235a respectively. Steel plate q235a products are most popular in Africa, Domestic Market, and Southeast Asia.
Q235B is the most common used among carbon steel.It is equal to steel grades ASTM A36,JIS G3101 SS400,EN 10025-2 S235JR.Xinsteel stocks carbon steel Q235B in coils shape and plate shape at port warehouses with many sizes.
Materials Q235A and Q235B belong to carbon structural steel. In the national standard GB700-88, the distinction between Q235A and Q235B material mainly in the carbon content of steel, the material is Q235A of steel, carbon content between 0.14-0.22%, Q235B of carbon content of steel between 0.12-0.20%;

ADVANTAGES OF COLD-FORMED STEEL - Cold-formed steel products are shaped at ambient temperatures from steel sheet, plate or flat bars by roll-forming machines, or press brakes. They can be produced in large quantity and at high speed with consistent quality.
Q235 steel is a Chinese GB standard plain carbon structural steel, and divided into 4 quality grades Q235A, Q235B, Q235C and Q235D, material density is 7.85 g/cm3, tensile strength is from 370 to 500 MPa, and yield strength is 235 MPa (tested with 16mm diameter steel bar or steel plate).
Roller tube: for belt conveyor roller welding steel pipe, generally use Q215, Q235A, B steel and 20 steel to manufacture, diameter is 63.5-219.0mm. It certain requirements on the tube bending, the end to the vertical line with the center line, the oval, and generally it must do water pressure and flattening test.
The user can identify the material on the label as Q235A steel plates, or Q235B steel plates, or other material. GB/T 700 Q235A steel plates have good ductility and plasticity, have a certain elongation, and have good welding performance and heat processing property. Q235A steel plates are generally used in hot rolling state.
A Q235A steel matrix sample was used in the wetting experiment with the 40mm40mm3mm dimensions and for the Bundy tube experiments the dimensions were 70mm20mm3mm. The che-mical compositions of the Q235A steel, as well as a new type of ux-cored solder named BAg25TS, are listed in Table 1.
