LT·H08MnA 2.5/3.2/4.0/5.0mm Submerged Arc Welding Wire

LT·H08MnA Conform to Standard :GB/T 5293 H08MnA

AWS Em12

ISO 14171-B-SU22

Specification:It is a kind of medium manganese-low silicon type welding wire,matches with medium-manganese and medium-silicon welding flux,Insensitive to rust on the base metal, It has excellent bead molding and slag detach ability.The wire can be applied single or dual feeding with AC/DC.

Purpose:Using with sintered flux LT•SJ101 , it can be applied both for high-speed welding steel plate of tensile strength 420N/mm2 and filling welding

Notes:
1. Shielding gas: Adopt pure Argon gas. Recommendation flow rate: 9-14L/min (AMP 100-200A), 14-18L/min (AMP 200-300A).
2. Tungsten extension: 3-5mm, Arc length: 1-3mm.
3. Wind speed limited: ≤1.0m/s.
Argon gas shielding on back side of welding part will get better welding result.
4. Mechanic property and metal anti-cracking ability of the welded metal relative by energy pass value on the wire.
5. The welding should be operated in clean surface without rust, moist, oil contamination and dust.The above suggestions are for reference purpose. Evaluate and determine the situation of the scene before starting the wielding process.

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

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
