Steel winter storage market difficult to reproduce, crude steel production continues to decline

Although winters in previous years have been the off-season for steel consumption, the winter storage market still offered hope for steel prices. However, the 2013 winter storage market is expected to underperform. The main reasons for this judgment are: a pessimistic outlook for the steel market, resulting in insufficient market willingness for winter storage; steel traders, having suffered losses, are short of funds, and tighter bank lending has further constrained their finances, making it difficult for them to engage in winter storage. Neither the motivation nor the ability supports steel traders and consuming enterprises to engage in winter storage.

"The steel pipe market will continue to grow, and the oversupply situation will ease."

How to calculate the yield point of seamless square tube

For metallic materials exhibiting yield phenomenon, the stress at which the specimen continues to elongate without any increase in force (the force remains constant) during tensile testing is called the yield point. If the force decreases, the upper and lower yield points should be distinguished. The unit of yield point is N/mm2 (MPa).
