Last week, the domestic steel market price fell from an upswing to a full fall. The steel market rebounded since the end of March has come to an end. Although demand for steel has risen in the recent peak season, market transactions have supported higher steel prices. However, with the short-term saturation of downstream purchasing space and the continuous decline in the forward prices such as ** and electronic trading, market confidence has been frustrated and end-users are gradually entering the wait-and-see phase. , high willingness to accept goods weakened. At the same time, the early traders huntered down resources ** operation increased, the steel price is not stable, pressure fell. On the whole, the current downturn in steel prices is due to the adjustment of demand after the market has soared. There has been no major change in the fundamentals.
As of April 18, Shanghai 8mmHRB400 plate coil transaction price was 3400 yuan / ton, compared with the previous weekend fell 50 yuan / ton; Ф6.5mmHRB235 high line transaction price was 3260 yuan / ton, compared with the previous weekend fell 40 yuan / t; The transaction price of Ф20mmHRB400 rebar was RMB 3,250/t, which was RMB 50/t lower than the previous weekend; the transaction price of 5.5* 1500 PSP was RMB 3,370/t, which was RMB 10/t lower than the previous weekend; 1.0* The price of 1250 Prairie was RMB 4040/ton, down RMB 10/ton from the previous weekend.
Last week, the performance of the capital market was poor, and the number of electronic discs continued to fall. It was a sharp dive near the weekend and the attitude of traders deteriorated. The wait-and-see atmosphere was getting stronger. At the same time, due to the favorable dilution of the previous period, the slowdown in demand recovery and the renewed bad news, the steel price continued to rise, and there was a situation where the price of the steel price rose. Coupled with the sharp rebound in steel prices, the lower reaches of the procurement of high-level resources are cautious, the market turnover has dropped significantly. However, due to the current support of raw material costs, market inventories remain downward, and steel prices are unlikely to drop sharply.
In terms of the short-term market, the author thinks that the following two factors need to be considered:
On the one hand, the news was bearish, resulting in insufficient confidence in the market outlook. From the economic data of the first quarter of this year, the growth rates of various indicators such as industry, investment, foreign trade, and domestic demand have all declined to varying degrees, especially since GDP has increased by 7.4% year-on-year, failing to reach the set target of 7.5%. capital market. And taking into account the overall regulatory ideas, the recent government is unlikely to introduce favorable stimulus measures. At the same time, market sources said that in the first quarter, the real estate market volume fell sharply, resulting in an increase in the bearish steel market, leading to the lack of confidence in the market outlook for businesses, price increases will increase shipping.
On the other hand, the resumption of production of steel plants has accelerated and supply pressure has increased. According to the latest data from the China Iron and Steel Association, the average daily output of crude steel in key steel enterprises in April was 1,747,300 tons, an increase of 78,300 tons, which rose by 4.69% compared with the previous period; the national average production of crude steel was 2,151,500 tons, an increase of 78,300 tons. The contract rose by 3.78% during the ten-month period. In the trend of keeping raw materials at a low level and spot prices continuing to rebound, the profitability of steel mills has increased, the production kinetic energy is sufficient, and the rate of production recovery has been accelerating, resulting in a significant increase in overall market supply pressure. At the same time, the recovery of demand for downstream steel has slowed down, the willingness to purchase has weakened, the contradiction between supply and demand has once again become apparent, and the market needs to find new balance after adjustment.
In general, the shrinking demand and the declining transaction result in the spot market falling sharply, while the increase in supply forces the steel price to face further pressure. In the short term, steel prices will continue to fluctuate slightly.
Because of its self forming or tapping the thread matching it, it has high anti loosing ability in combination and can be disassembled. In the small screw, its size, thread type, head type, drilling performance, in the engineering use of high tension, single, unilateral combination features almost unlimited. Self tapping materials can be divided into carbon steel and stainless steel, of which 1022 medium carbon steel is the main material.
1: According to the different head, it can be divided into: round head, flat head (i.e. countersunk head), top stigma, round top wide side head, big round head (i.e. big flat head), hexagon bearing hole head, hexagon bearing hole Huasi head, hexagon bearing hole Huasi head
Round head: it is the most commonly used head shape in the past
Flat head: it can replace the new design of round head and mushroom head. The head is low in diameter, and the peripheral circumference of the head is connected with the high edge of the characteristic, which makes it play a driving role for high-strength torque. It is slightly different from the hole head in head shape
Top column head: the diameter of the standard flat round top column head is smaller than that of the round head, but it is higher due to the groove depth. The smaller diameter increases the pressure acting on a small area, and can be closely combined with the flange and the increased surface layer. As the head is made in the drilling die set to ensure the concentration, they can be successfully applied to the holes in the internal drilling
Dome wide side head: due to the undercutting of the head to restrain and reduce the wear of the wire components, it is most commonly used in electrical appliances and tape recorders, providing an attractive design type for the middle and low head type with its more sufficient bearing surface
Big round head: also known as oval top wide edge head, is a low type, cleverly designed large diameter head. When the combined tolerance of additional function allows, it can be used to cover the metal plate hole with larger diameter. It can also be recommended to use flat head instead
Hexagon socket head: a kind of joint with the height of wrench head and the size of hexagon head. The hexagon is completely cold formed by the reverse hole mold, and there is an obvious depression at the top of the head
Hexagon socket head: such as the standard hexagon socket head, but at the same time, there is a socket face on the base of the head to protect the assembly from damage of the wrench. Sometimes the function of things is far more important than appearance
Hexagon head: This is a standard type of torque acting on the hexagon head. It has the feature of trimming sharp corners close to the tolerance range. It can be recommended for general commercial use. It can also be applied to various standard patterns and various thread diameters. Because of its necessary second process, it is more expensive than general hexagon socket
2: According to the groove type, there are four types: slotted head type (also called slotting), cross slotted head type, cross slotted head type, cross slotted compound slotted head type and meter slotted head type
3: According to the standard can be divided into: GB, DIN, ANSI, BS
