Submerged Arc Welding Flux for Steel Structure (sj101)

Basic Info

Model No.:  sj101

Product Description

Model NO.: sj101 pH: Alkaline Melting Point: >600℃ Function: Protect Weld Metal Manufacturing Method: Agglomerted Grain Size: 10-60 Meshes Color: Grey Suitable: Low Carbon Low Alloy Steel Payment: Tt or LC Port: Qingdao Specification: sj101 state: Solid Type: Inorganic Chemical Composition: SiO₂=10%-30% Application: Submerged-arc Welding Kind: Fluorine Alkali Performance: Easy to Deslag Usage: Weld Structure Steel, Pressure Vessel etc Delivey: 15-20 Days Packages: Paper Bag or Pallet Trademark: trustworthy Origin: Shandong China Submerged arc Welding Flux

Description: 
1.the welding flux is fluorine alkali type sintered flux. 
2. Grain size: 10-60(2.0-0.3mm) meshes. 
3. Performance: 
A. Easy to deslag. 
B. Sulfur removal, phosphor removal and anti-rust. 
C. Fine appearance of weld (even in the narrow gap of deep slope entrance). 
D. Metal welding seam: Good plastic toughness, low hydrogen content diffusion and fine properties of cold, heat and crack resistance. 

Usage: 
1. welding flux is For low carbon, low alloy and pipeline steel. 
2. welding flux is For thick wall structures of different high-tensile steels. 

Cautions: 
1. The oil contamination, moisture, iron rust and other foreign substances must beremoved from the welding joint. 
2. It is better to weld under direct current. 
3. Welding flux must be baked under 250-300°C for more than 2 hours
Before usage.
