600-2500mm Carbon Steel Sheet Bridge board: Q235qc, Q235qd, Q345qC,
Q345qD, Q345qE
1. Carbon structural steel
Example q235-A ·F, σ S ≥235MPa note: Q is yield strength A quality
grade (ABCD 4), F Boiling steel features: low price, excellent
process properties (such as weldability and cold formability).
Applications: General engineering structures and general machinery
parts. Such as Q235 can make bolts, nuts, pins, hooks and less
important mechanical parts and building structures in the rebar,
steel, steel bar, etc
2. High quality carbon structural steel
Application: Non-alloy steels used in the manufacture of important
mechanical parts are generally used after heat treatment. Common
steel number and use: 08F, low carbon mass fraction, good
plasticity, low strength, used for stamping parts such as
automobile and instrument shell; 20, good plasticity and
weldability, used for strength requirements are not high parts and
carburizing parts, such as machine cover, welding container, small
shaft, nut, washer and carburizing gear; 45,40 Mn, good
comprehensive mechanical properties after quenching and tempering,
used for mechanical parts with large force, such as gears,
connecting rods, machine tool spindles, etc. 60, 65Mn steel has
high strength; Used for manufacturing various springs, locomotive
rim, low speed wheels.
