Reasons for Analysis

According to the statistics from 51 Stainless Steel, the 300 series cold rolling accounts for 40.66% of the total inventory this time. More than 75.63% of the 300 series cold rolling in our specimen inventory is 304 wide cold rolling, so our inventory analysis this time mainly focuses on the 300 series:

Analysis 1:

From the perspective of resource structure, the arrival of goods exceeds the consumption, leading to a slight surplus in inventory. Within a week's cycle, the new resources are evident as the arrival of goods from Delong, and there are also small amounts of new goods from Qingtuo Shangke, Hongwang, and Yongjin in the inventory, with the rigid demand and the pace of goods arrival basically consistent.

Analysis 2:

With the market downturn, market transactions have slowed down, and the digestion speed has decreased.

Analysis 3:

Recently, there has been an increase in the closure of downstream factories and enterprises, coupled with business adjustments among market plate merchants. Plate merchants controlling risks have also had some impact on shipments.

Analysis 4:

Export processing volume is stable, so the driving force for inventory reduction is limited.

Inventory Data

The time for collecting specimen inventory data this time is: cold rolling on July 16th, hot rolling on July 17th. Note: Specimen warehouse inventory does not include delivery warehouse inventory.

This week's total specimen inventory is 376,600 tons, an increase of 1,600 tons from last week, an increase of 0.43%. Among them:

  • 200 series inventory increased to 134,800 tons, an increase of 700 tons from last week, an increase of 0.52%;
