GB/T 5118-2012Covered electrodes for manual metal arc welding of creep-resisting steels (English PDF)

Foreword

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

This standard is GB/T 5118-1995 "low alloy steel welding rod," the amendment. Compared with GB/T 5118-1995, the main content as follows.

--- This revision only retained the original standard carbon steel electrode molybdenum and chromium molybdenum steel welding rod, and model preparation, technical requirements were phase should be adjusted accordingly. Original standard nickel steel, nickel-molybdenum steel, manganese and molybdenum in steel electrode Model E5515-D3, E5516-D3, E5518-D3, which His low-alloy electrode Model the E5018W, E5518W and other technical requirements to the new electrode revised GB/T 5117 "non-cooperation Magic and fine-grained steel welding rod "standard;

--- Electrode and classification models according to ISO 3580:2010 carried out;

--- Increased 2C1MV, 3C1MV, 5CM, 5CML, 5CMV, 7CM, 7CML, 9C1M, 9C1ML, 9C1MV, 9C1MV1 and other chemical composition;

--- Drug skin types retain the special type of "00", according to ISO drug skin type is changed to "40";

--- For reservations GB/T 5118-1995 the E5500-B1 (model designation for the E5540-CM), E5503-B1 (model designation the E5503-CM) and other 10 models electrode, the deposited metal tensile strength and yield strength of the electrode by other appropriate models Requirements of the regulation, the Elongation was appropriate to reduce the deposited metal chemical composition according to claim other types of welding rod, S, P Adjusted to not more than 0.030%;

--- Remove the technical requirements for drug skin moisture content;

--- Remove the impact test requirements;

--- With ISO 3580:2010 corresponding to the type of electrode according to the technical requirements of ISO 3580:2010 has been adjusted.

This standard uses redrafted law revision of international standards ISO 3580:2010 "welding materials heat resistant steel SMAW medication skin Electrode Classification "(in English).

This standard ISO 3580:2010 and its main technical difference between the following reasons.

--- Remove the International Standards Normative documents referenced in direct reference to domestic standards, China has transformed accordingly, in order to carried out;

--- According to China's actual application, the deposited metal tensile code "49" to "50" In our technical conditions applicable;

--- Retained E5500-B1 (model designation for the E5540-CM), E5503-B1 (model designation for the E5503-CM), E5500-B2-V (Model designation as E5540-1CMV), E5515-B2-V (model designation as E5515-1CMV), E5515-B2-VNb (Model Preparation of E5515-1CMVNb), E5515-B2-VW (model designation as E5515-1CMWV), E5500-B3-VWB (type Preparation No. E5540-2CMWVB), E5515-B3-VWB (model designation as E5515-2CMWVB), E5515-B3-VNb (model designation as E5515-2CMVNb), E6000-B3 (model designation as E6240-2C1M) and other 10 electrodes Model, its technical requirements have been adjusted to apply our technical conditions;

--- Increased drug skin types 03 and 40 are two types, to apply to our technical conditions;

--- Chemical composition types increased 1CMV, 1CMVNb, 1CMWV, 2CMWVB, 2CMVNb, 5CMV, 7CM and 7CML eight types to apply our technical conditions;

--- Retained ray testing requirements of weld metal to apply our technical conditions;

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

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

--- Standard name changed to "heat resistant steel electrode";

--- Standard structure, by category and type, technical requirements, test methods, inspection rules, packaging, marking and quality certification be written.

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