GB/T 983-2012Covered electrodes for manual metal arc welding of stainless and heat-resisting steels (English PDF)

Foreword

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

This standard is GB/T 983-1995 "stainless steel welding rod," the amendment. Compared with GB/T 983-1995, the main content as follows.

--- Electrode and classification models according to ISO 3581:2003 carried out;

--- Remove the electrode deposited metal chemical composition of the chromium content of less than 11% of the E502-XX, E505-XX, E7Cr-XX, E5MoV-XX, E9Mo-XX, E11MoVNi-XX and E11MoVNiW-XX seven electrodes Model;

--- E317MoCuL-XX model prepared for the E317LMoCu-XX;

--- E318V-XX, Cu content E330MoMnWNb-XX and E16-25MoN-XX three types of electrodes from 0.5% adjustment to 0.75%. Si content E318V-XX by no more than 0.90 percent to 1.00%, S content of 0.030% by the adjusted 0.03%, to maintain consistency with the E318-XX; the chemical composition of other types of electrode according to ISO 3581:2003 has been adjusted accordingly;

--- Increasing the welding position "4", suitable for all position welding including vertical down welding;

--- The mechanical properties of the electrode according to the requirements of ISO 3581:2003 has been adjusted.

This standard uses redrafted law revision of international standards ISO 3581:2003 "welding materials stainless steel and heat-resistant steel electrode arc Coated electrode welding medication classification "(in English).

This standard ISO 3581:2003 and its main technical difference between the following reasons.

--- Remove the International Standards Normative documents referenced in direct reference to the corresponding national standards, China has transformed easy carried out;

--- Not use electrodes Model "ES" on behalf of stainless steel welding rod, still use the "E" on behalf of the electrode, to facilitate the actual operation;

--- Retained E317MoCu-XX, E317MoCuL-XX, E318V-XX, E330MoMnWNb-XX and five E16-25MoN-XX A welding rod models, the technical requirements for the corresponding adjustments to adapt to China's technical conditions;

--- Increased E309H-XX, E316LMn-XX, E2594-XX, E2595-XX, E3155-XX and E33-31-XX six electrodes Models to meet the actual application requirements;

--- Retains the rod eccentricity Technical indicators to facilitate handling;

--- Retains the weld metal corrosion resistance and the technical requirements of the weld ferrite content in order to apply our technical conditions.

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

--- Standard name was changed to "stainless steel electrode";

--- Standard structure, by category and type, technical requirements, test methods, inspection rules, packaging, labeling and quality certificates were write.

This standard by the National Standardization Technical Committee welded (SAC/TC55) and focal points.
