TECHNICAL REQUIREMENTS:GOST 9466-75, TU BY 100034500.029-2011

COATING:main

PURPOSE:

For the welding of corrosion-resistant austenitic steels 08Cr18Ni10Ti marks 12X18H10T, 10X17H13M2T and the like, when weld metal imposed resistance requirements for intergranular corrosion and operating in liquid corrosive non-oxidizing environments at temperatures up to 350 ° C and does not undergo heat treatment after welding, and and overlaying the second layer on the surface of the article from pearlitic.

In all spatial positions except the vertical "top-down", at a constant current of opposite polarity.

CHARACTERISTICS Electrodes:

arcing	sustainable
splashing degree	small
formation of the joint	a good
Separation of the slag crust	satisfactory
deposition rate (in the lower position of the weld)	10.0 - 12.0 g / Ah
deposition rate (electrode diameter 4.0 mm)	1,5-1,7 kg / h
Electrode consumption per 1 kg of weld metal	1.8 kg

Typical mechanical properties of weld metal (at 20 ° C):

Type of heat treatment (t / a)	Tensile strength, MPa	Relative extension, %	Impact toughness J / cm2
Without t / o	550	25	85

Chemical composition of deposited metal:

Element content, weight%
Carbon	Silicon	Chromium	Manganese	Nickel	Molybdenum	Vanadium	Sulfur	Phosphorus
<= 0.10	<= 0.60	16,8-19,0	1,1-3,1	9,0-12,0	2.0-3.5	0,30-0,75	<= 0.025	<= 0.030

DIRECTIONS FOR USE:

Before welding, the surface to be welded must be cleaned to metallic luster.

In case of exceeding the permissible moisture content in the coating (0.3%) before use further electrodes are calcined at a temperature of 280-300 ° C for 40 minutes.
