When the amount of vanadiumor columbium is less than 0.008 %, the analysis may be reported as 0.008 %.5.2 Where material is used for fabrication by welding, care must be
22、exercised in selection of the chemical composition to assurecompatibility with the welding process and its effects on altering the properties of the steel.6. Bending Properties6.1 The minimum forming radius (radii) which steel covered by this specification can be expected to sustain is listed in the
23、appendix and is discussed in more detail in Specifications A568/A568M and A749/A749M. When tighter bend radii are required,or curved or offset bends are involved, or when stretching or drawing are also a consideration, the producers shall be consulted.7.
