【 material description 】
Q195-235 - b square tube, Q235B pipe, Q345B, # 20 square pipe, rectangular pipe, rectangular pipe, the rectangular steel tube (hollow cold bending steel), galvanized, etc., produce all kinds of material and the torque tube. 3087/5310/9948 / alloy series, stainless steel, square tube, please telephone consultation
【 properties 】
Under the condition of plane bending of rectangular tube bending strength big, square tube rolled strip after processing. Generally is the strip after unpacking, smooth, curly, form circular tube welding, again by circular tube rolling into square tube and then cut into required length. Is generally 50 per package. Execution standard: GB/T6728-2002, GB/T6725-2002, GBT3094-2000, JG 178-2005, ASTM A500 featured JIS G3466, EN10210
Q345B square tube corresponding to the old GB/T1591-1988 high strength low alloy structural steel, 16 mn brand, in the new national standard GB/T1591-1994 grades for Q345 (Q345 with five levels of quality, Q345A ~ Q345E), Q345A corresponding ASTM brand is a Gr, 50 in the United States.
Used in construction, machinery manufacturing, steel construction, shipbuilding, solar power stents, steel structure engineering, power engineering, power plants, agricultural and chemical machinery, glass curtain wall, construction steel structure, large stadium, exhibition center, lifting machinery, shipbuilding, storage shelves, decoration, traffic facilities, airports, railway vehicle, bridge bracket, mine bracket, three-dimensional garage, outdoor advertising, fitness equipment, wind power equipment, vehicle manufacturing and other industries
【 data reference 】
The chemical composition of Q195 square tube
C: 0.12% Mn or less: 0.50% or less Si: 0.30% or less: S P 0.040% or less: 0.035% or less deoxidization methods: F, b, Z, tensile strength (sigma b/MPa) : 315-430, the yield strength of 195 MPa. Than the strength of Q235 low
The chemical composition of Q235B square tube
C: 0.20% or less Si: 0.35% Mn or less: 1.4% or less: S P 0.045% or less: 0.045% or less deoxidization methods: F, b, Z, tensile strength: 370-500, the yield strength of 235 MPa. Is lower than the intensity of Q345
The chemical composition of Q345B square tube
C: 0.12-0.20; Mn: 1.20-1.60; Si: 0.20-0.55; Tensile strength: 470-660; Yield strength: 275-345 mpa. According to the specific values of steel thickness or diameter, the above data corresponding to the thickness of the steel or diameter: 16 mm detection
(Q345, series is divided into A/B/C/D/E level, A representative not do impact test, B on behalf of the normal temperature is 20 degrees do impact test, C representative 0 degrees do impact test, D representative minus 20 degrees do impact test, E do impact test on behalf of 40 degrees below zero, the former more than A/B used as steel structure, and the latter more than C, D, E used as used in the different temperature conditions.) 3087/5310/9948 / alloy series, stainless steel, square tube, please telephone consultation: +8613102049996.
