MCC-owned China Metallurgical Construction Research Institute Co., Ltd. "-70 ℃ low temperature steel electrodes W707Ni with the development" through appraisal.

Low temperature steel Welding Wire is low-temperature equipment, cryogenic storage tank area with one of the main varieties of welding consumables, welding area is high-end products. In order to change our long-standing dependence on imports of such electrodes over the situation, in Yejian research tackling the technology more than two years to complete the -70 ℃ low temperature steel electrodes W707Ni with the development.

Appraisal meeting, listen to the report by the Expert Committee, question the respondent and rigorous evaluation, agreed that: the Yejian research "-70 ℃ low temperature steel welding rod W707Ni" compared with similar products, with excellent low temperature impact resistance of -70 ℃, good low temperature crack resistance, fracture mechanics performance and innovation in NDTT (non-plastic transition temperature) indicators, has reached the advanced level of similar products.

The technical results related products to fill the domestic blank, the field of Cast Iron Welding Wire at low temperatures have great promotional value.
