The Q345 is a steel with less than 0.2 percent of its composition made up of carbon, less than 0.55 percent of its composition made of silicon and several impurities. This particular grade of steel is a general purpose manufacturing steel in construction equipment field. Yield Strength
Q345 Steel Properties and Introduction. Q345 steel is a Chinese GB standard Low Alloy High Strength Structural Steel, material density is 7.85 g/cm3, tensile strength is 470-630 Mpa, and yield strength is 345 MPa. According to GB/T 1591 2008, Q345 material has 5 quality grades: Q345A, Q345B, Q345C, Q345D and Q345E.
Q345 steel is an alternative to the old steel grades of 12MnV, 14MnNb, 18Nb, 16MnRE, 16Mn, etc., and it is not just a substitute for 16Mn steel. In terms of chemical composition, 16Mn and Q345 are also different. More importantly, there is a large, q345 grade
Q345 structural steel has good mechanical properties, low temperature performance, plasticity and good weld ability, Q345 steel is mostly used in low pressure vessel, oil tank, vehicles, cranes, mining machinery, power stations, mechanical parts, building structure, and general metal parts. Q345 Steel Chemical Composition:
This particular grade of steel is a 'general purpose' manufacturing steel in construction equipment field, such as Q345B is basic mateiral of making excavator bucket and Excavator long reach booms. The major benefit of this grade of steel is its mild temper. It's easy to form and easy to weld, Mechanical Properties. 1, Yield Strength
European equivalent grade for Non-alloy quality structural steel Q345B (GB ): S355JR (1.0045) NEW opportunities for buyers! Post free buying requirement for product Q345B (GB ) Chemical composition and properties of european equivalents (EN) for Q345B (China, GB ): S355JR (1.0045) ,
Steel grade Q345B is the most common used as high strength low alloy structural steel in industry area.Xinsteel can offer steel coils,steel plates,angles,channels for Q345B materials.The equivalent steel grade with Q345B are EN 10025-2 S355JR,ASTM A572/A572 A572 Grade 50 and DIN 17100 St52-3.
Grade Q345 Imported Tube does not conform to grade S355. It has come to the attention of the ASTPM that Grade Q345, a standard in China, is being sold into the local market as equivalent to S355. An investigation into Q345, including a number of tests, has resulted in the following conclusions.
A36 steel plate is similar to Q235B steel plate, it is one Q235b equivalent steel standard, another one is SS400. , q345 grade Although the Q235 steel grade steel plate has lower mechanical properties than A36 and SS400 material, but in actual operation process, as long as the buyers do not have special requirement, often these three kinds of materials , q345 grade
Steel Grade Equivalent Table (EN, SAE/AISI, UNS, DIN, BS, UNI, JIS) The table below compares common grades of materials from various international specifications. Note that materials compared are the nearest available grade and may have slight variations in actual chemistry.
Properties of Q345B Steel for Plate Material , q345 grade Chances are, if you've got an object with a steel exterior that was made in China, this is the grade of steel used for the outside of it. It is the combination of comparatively low price and ease of use that makes this steel nearly ubiquitous in consumer goods where low weight isn't a major concern.
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:

There are number of different grades of Q345 Steel going from A to E.  They appear to be base on variations of AISI 1020 or 1018. China is controlling a number of elements that are not normally controlled in these steels in the USA. It would also come under the general heading of low alloy or Low Carbon Steel. Niel Leon
Q355 Steel Introduction. Q355 steel is a new Chinese steel grade of Low Alloy High Strength Structural Steel, which replaced Q345, the material density is 7.85 g/cm3.According to GB/T 1591 -2018, Q355 has 3 quality levels: Q355B, Q355C and Q355D..
