This week, the national cement price was down 0.17% from last week

This week, the national cement market price was lowered by 0.17% from last week.

The price of cement and clinker in Hunan Chang-Zhu-Tan area increased by RMB 30/t this week, which is now Changsha P. 042.5 bulk price in place 420-430 yuan / ton, clinker price 340 yuan / ton.

Reasons for the price increase: On the one hand, due to the price drop of individual companies in the previous period, in order to prevent the general price decline, the leading enterprises increased the price through the recent increase in demand; on the other hand, the company considers that the demand will be lower after the market opens next year. The fall is inevitable, and raising the price base, even if the price has fallen, can be relatively maintained at a high level.

This week's performance varies from north to south in Jiangsu Province, with prices rising and falling. The prices of cement in southern Suzhou, Wuxi, and Changzhou were all increased by 20-30 yuan/ton, and the price of Nanjing was temporarily stable (it is estimated that the price will increase by 20 yuan/ton in the next two days).

Reasons for the price increase: After the suspension of production in the previous period, the pressure on the current company's inventory has been reduced, which is basically around 60%. The number of companies that have stopped production is quite large, and the time for resuming production is about to reach the 10th, so the short-term price increase conditions are met. The price of Jiangsu Xuzhou, Lianyungang, Suqian, etc. in northern Jiangsu was lowered by RMB 10-15/ton, and the price basically fell back to the level before the price increase in October. Reasons for price cuts: At the end of the year, the profit targets of various companies have been basically completed, the willingness to reduce production has decreased, the pressure on the stocks has increased, and prices have come back. The synchronization between southern Shandong and northern Jiangsu.

The price hike in Nanchang, Jiangxi Province, failed to be successful, and all of the above-mentioned enterprises have been restored to their original positions, and there have been recurrences. From the track of the situation, the current situation of various companies returning customers varies from 20-60 yuan / ton, P. 042.5 Dispersed into the mixing mainstream price is 410 yuan/ton.

After entering the winter, Xinjiang's prices experienced a seasonal fall, with a margin of RMB 30/t.

Duplex Stainless Steel Overview

Duplex Stainless Steels, also referred to as austenitic-ferritic stainless steels, are a family of grades with about equal proportions of ferrite and austenite. These steels have a duplex microstructure which contributes to their high strength and high resistance to stress corrosion cracking. Due to their high content of chromium, nitrogen and molybdenum, duplex steels offer good resistance to local and uniform corrosion. Duplex stainless steels have good weldability.


Today, modern duplex stainless steels can be divided into three groups:
Lean Duplex such as LDX2101
Standard Duplex such as 2205, the work-horse grade accounting for more than 80% of duplex usage
Super Duplex such as Ferralium 255 and Zeron 100 and LDX2507

Of the duplex grades, duplex 2205 is the most widely used. However, the super duplex steels like Zeron® 100 and LDX2507 are excellent for servicing severe corrosive environments, such as offshore and marine applications. Lean duplex 2101 is available as an economic alternative to 300 series stainless steels.
