Foreword

This standard rule according to GB/T 1.1-2009 given draft.

This standard replaces GB/T 3282-2006 "titanium-iron." the main changes in the standard of GB/T 3282-2006 compared as follows.

--- The FeTi50-A, FeTi50-B, FeTi60-A, FeTi60-B, FeTi70-C, FeTi80-A, FeTi80-B and eight FeTi80-C Grades inclusion criteria;

--- Modified FeTi30-B, the carbon content FeTi40-B and FeTi70-C grade product requirements;

--- Modified silicon FeTi70-B and FeTi70-C grade products, aluminum content requirements;

--- Modified FeTi30-B, phosphorus content FeTi40-B grade product requirements;

--- Modified sulfur content FeTi70-B grade product requirements;

--- Modified FeTi30-A, manganese, copper content FeTi40-B and FeTi50-B grade product requirements;

--- Modify the product size requirements.

This revised standard adopts the International Standard ISO 5454. 1980 "Ferrotitanium specifications and delivery conditions" (in English).

This standard is based on ISO 5454. 1980 redrafted listed in this standard reg numbers in Appendix A and ISO 5454. 1980 chapter Article number of the control list.

Adopting ISO 5454. 1980, the present standard do some modifications relating to technical differences have been incorporated into the text in which they are involved.

Terms of the margin with a single vertical line identified in Appendix B gives a list of these technical differences and the reasons for the reference.

For ease of use, ISO 5454. 1980, this standard also made the following editorial changes.

--- The "this International Standard" be replaced by "this standard";

"." --- By decimal points instead of ISO 5454. 1980 for use as a decimal point, "";

--- Remove ISO 5454. 1980 Foreword.
