Co2 Copper Coated MAG Welding Wire ER70S-7 .023" 0.6mm 0.8mm

GMAW LT*ER70S-7 0.8/1.0/1.2/1.6mm Cooper Coating Welding Wire

GMAW ER70S-7 is a general purpose MIG wire suitable for many carbon steel welding applications but with substantially greater manganese content than ER70S-3 welding alloy. The higher manganese provides slightly better wetting and weld appearance with slightly higher tensile and yield strengths as well. These combined properties permit increased speed when compared to S-3 product. Under equivalent welding conditions,
ER70S-7 produces as weld hardness lower than ER70S-6 but higher than ER70S-3

Typical Applications
• High tensile strength steels for automobiles
• Rolling stock
• Electrical appliances
• Machinery
• Air conditioners
• Light gauge steels
• Pipes
• Steel frames

Longteng Special Steel Group is a well-known private enterprise in China's special steel industry. Founded in 1993, it is a deep processing enterprise of metal products integrating sintering, ironmaking, steelmaking, refining, continuous casting, rolling and metal product processing. It has an annual output of 4.5 million tons of various special steels and its products are sold to more than 40 countries and regions. Longteng Special Steel Group has ten major business segments. Its leading products include: hot-rolled Marine sections, prestressed concrete (PC) steel bars, high-end wear-resistant steel balls, high-end welding materials, oil and gas pipe fittings, new energy forgings, medium and heavy plates, etc.
Among them, the three major products of Marine steel sections, PC steel bars and wear-resistant steel balls have all become the largest production bases in China, with market shares of over 60% in the domestic niche industries. Among them, wear-resistant steel balls have become the second largest supplier in the world's grinding industry

7: Steel thick plate

As part of our development strategy, we have always been focused on the complete production process model. We believe this will bring us synergy effects. Therefore, recently, a new product, namely welding consumables, has been added to our catalogue. It will cover all series such as gas shielded solid welding wires, flux-cored welding wires, submerged arc wires, argon arc wires, etc., as well as medium and heavy plate series (thickness 6-800mm). Width: 1500mm-3650mm, maximum single weight: 60t

Our LT welding wire has two main advantages:
A fully integrated production process, that is, supported by the world-class upstream steel manufacturing facilities of the same group company.
The newly developed production process, which adopts the latest technologies and know-how, namely fully automatic production, will ensure quality control.
Our advantages of medium and heavy plates:
Complete electric furnaces and off-furnace refining equipment
The rated capacity of the ultra-high power electric furnace is 115 tons, and the maximum steel output per furnace is 130 tons
It has two 115-ton LF refining furnaces and one double-station VD furnace
The largest-sized steel ingots and continuous casting billets
The largest flat steel ingot is 60 tons, and the largest plum blossom steel ingot is 270 tons
The maximum single weight of the ingot steel plate: 60 tons (forged and rolled combined process)
Continuous casting adopts the techniques of dynamic light pressing, dynamic secondary cooling and heavy pressing
The maximum cross-sectional specification of the continuous casting billet is 460*2600*3600mm
Complete rolling line equipment
Advanced split vertical rolling mill
