Dec 12, 2019 · Some foreign customers are often confused about GB Q345 steel. Q345 low alloy high strength steel is the replacement steel of old GB grade 12MnV, 14MnNb, 18Nb, 16MnRE, 16Mn, etc. The chemical element is similar to 16Mn, and Q345 increases the micro-alloy element V, Ti and Nb which refines the grain, greatly improving the toughness and comprehensive mechanical properties of steel, Fast Automatic Measurement of Mechanical Properties of SteelAfter some improvements method can be used for e tests during production of railway wheels, tyres, thick plates, rails, beams etc. It also can be used in handheld devices for high-stressed steel constructions tests, like high-pressure and high-temperature pipelines, where mechanical properties may degrade with time.

Usage. The steel grades of the S315MC to S700MC series are used for cold-formed components of the most varied designs. The user of these steel grades must make sure that his calculation, design and processing methods are appropriate for the material. The forming process used must be suitable for the intended application and comply with the Introduction and application of Q345 low alloy steel - EB Jul 22, 2019 · Introduction and application of Q345 low alloy steel. Q345 is a low-alloy steel widely used in Bridges, vehicles, ships, construction, pressure vessels, special equipment, etc. Q means yield strength and 345 means yield strength of this steel is 345MPa.Of the low alloy materials, Q345 is the most common. Q345 used to be called 16Mn.
Mar 21, 2016 · 2. 1 Preparation for the experiments. Test samples are obtained from steel plates of Grade Q345GJ-C with the thickness of 60 mm, 80 mm, 100 Q195 Steel Chemical Composition, Mechanical Properties Q195 Steel Properties and Introduction. Q195 steel is a Chinese plain carbon structural steel, yield strength:195 MPa, tensile strength:315-430 MPa, material density:7.85 g/cm3. Q is the first letter of Chinese spelling of qu fu dian, the translation is Yield Point or Yield Strength, 195 is indicates the unit value 195 MPa.

Alro Steel Metals Guide Steel Plate & Sheet ASTM A-514 Plate *This grade of steel may be susceptible to cracking in the heat-affected zone of welds during post-weld heat treatment (stress relief). Careful consideration should be given by competent welding engineers before stress relieving to Steel properties at low and high temperatures ::Total Figure 2. Effect of low temperatures on the mechanical properties of steel in plain and notched conditions. Surface grinding with grit coarser than 180 and shot-blasting causes embrittlement at -100°C due to surface work-hardening, which, however, is corrected by annealing at 650-700°C for 1 h.
