Product Introduction
- Pickling plate and picked steel board are intermediate products between hot-rolled and cold-rolled plates, which are made of high-quality hot-rolled thin plates as raw materials. After removing the oxide layer, cutting edges, and finishing by an acid washing unit, the surface quality and usage requirements (mainly cold bending or stamping performance) are between hot-rolled and cold-rolled plates. They are ideal substitute products for some hot-rolled and cold-rolled plates. Compared with hot-rolled plates, the advantages of acid washed plates mainly lie in: 1) good surface quality. As hot-rolled acid washed plates remove surface oxide scales, the surface quality of the steel is improved, making it easier to weld, oil and paint. 2) High dimensional accuracy, after leveling, can cause certain changes in the shape of the board, thereby reducing the deviation of unevenness. 3) Improved surface smoothness and enhanced appearance effect. 4) Can reduce environmental pollution caused by dispersed acid washing by users. Compared with cold-rolled sheet, the advantage of acid washed sheet is that it effectively reduces procurement costs for users while ensuring surface quality requirements for use. At present, many enterprises have increasingly high requirements for high-performance and low-cost steel. With the continuous advancement of steel rolling technology, the performance of hot-rolled thin plates is approaching that of cold-rolled plates, enabling the technological realization of "replacing cold with heat". It can be said that pickling plate is a product with a relatively high cost performance ratio between cold-rolled plate and hot-rolled plate, and has good market development prospects
1. Reducing costs by using pickled plates instead of cold-rolled plates can save costs for enterprises.
2. The surface quality is good. Compared with ordinary hot-rolled plates, hot-rolled pickled plates remove surface oxide scales, improve the surface quality of steel, and facilitate welding, oil coating, and painting.
3. High dimensional accuracy, after leveling, can cause certain changes in the shape of the board, thereby reducing the deviation of unevenness.
4. Improved surface smoothness and enhanced appearance effect.
- Fine selection of materials, direct supply of steel, favorable prices, and complete specifications.
- Excellent material selection, good transportation quality, and not easily damaged by external compression.
- We can process and customize according to customer requirements, and the specifications and dimensions can be customized.
1. The main applications of hot-rolled pickling in the automotive industry are as follows: automotive chassis systems, including main beams, auxiliary beams, etc. Wheels, including wheel rims, wheel radiation, etc. Cab interior panel. Carriage board, mainly refers to the bottom plate of various trucks' carriages. Other stamped parts, including collision bumpers, brake pads, and other small internal components of automobiles.
2. The mechanical industry (excluding automobiles) mainly includes textile machinery, mining machinery, fans, and some general machinery.
3. Light industrial household appliances are mainly used to manufacture compressor shells, brackets, water heater liners, etc. Chemical oil drums.
4. Other bicycle parts, various welded pipes, electrical cabinets, highway guardrails, supermarket shelves, warehouse shelves, fences, iron ladders, and stamped parts of various shapes.

Frequently Asked Questions
What trade methods and delivery scopes are supported by the steel products of Xiamen Xinghuibin?
With the business qualifications of goods import and export and technology import and export, Xiamen Xinghuibin can support various trade methods corresponding to international trade terms such as FOB (Free On Board), CIF (Cost, Insurance and Freight), and CFR (Cost and Freight). The delivery scope covers the whole country, providing national shipping services. At the same time, overseas delivery can be arranged according to the needs of international orders, based on integrity, ensuring quality and delivery time.
What is the fatigue strength of steel? For which application scenarios is it particularly important?
Fatigue strength refers to the maximum stress value that steel can bear without fatigue failure under the action of alternating load (cyclic load), which is usually lower than the static strength. This indicator is particularly important for scenarios bearing repeated loads, such as bridges, mechanical drive shafts, railway tracks, etc. The relevant profiles supplied by Xiamen Xinghuibin have undergone strict testing to ensure that the fatigue strength meets the safety standards of the corresponding scenarios.
How to perform surface rust prevention treatment on the steel supplied by Xiamen Xinghuibin? What are the common methods?
The steel supplied by Xiamen Xinghuibin mainly adopts the following surface rust prevention treatment methods: 1. Galvanizing (hot-dip galvanizing, electrogalvanizing), forming a zinc layer on the surface to isolate air and moisture; 2. Sandblasting, removing surface scale and impurities to enhance coating adhesion; 3. Painting/spraying, forming an anti-corrosion coating. Different treatment methods are suitable for different environments and can be customized according to customer needs to extend the service life of steel.
