2mm 3mm Hot Rolled Mild Steel Plate Q235 Q345b DC01 Cold Rolled
Steel Coil
Carbon structural steel,Grade: 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 performance (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.High quality carbon structural steel,Grade: Example 45, 65Mn,
08F. Brand note: direct expression of metal carbon content of ten
thousand fractions. Application: Non-alloy steels used in the
manufacture of important mechanical parts, usually after heat
treatment.
Common steel numbers and uses: 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.
