409L Stainless Steel Sheet
Grade 409 (UNS S40900, EN1.4512) is a stabilized version of 409, consisting of a suitable circuit, low levels of carbon and nitrogen, and additions All the right ingredients give Grade 409L some of the properties such as corrosion resistance, weldability, and formability - due to the lower chromium content, Grade 409L is another low-cost option for corrosion-resistant stainless steel.
and formability - With its lower chromium content, Grade 409L is another low-cost alternative to corrosion-resistant stainless steels.
It offers a good combination of heat and corrosion resistance and is well suited for non- or mildly corrosive environments or applications with excellent oxidation resistance at elevated temperatures and good weldability for use in automotive exhaust or petroleum equipment.

SS 304 Square Pipe
SS 304 Square Pipe is an excellent choice for most fabrication techniques as well as indoor and outdoor applications. This non-magnetic product features a semi-smooth, dark gray finish and tapered edges that are dimensionally accurate throughout its length.304 Stainless Steel is a high-strength material with excellent corrosion resistance, making it ideal for marine equipment, railings, medical devices, and food industry equipment. ASTM A554 is the standard specification for welded stainless steel mechanical tubing.

Application:
1. Home decoration

Home decoration is the place where stainless steel decorative tubes are most commonly used. We have a lot of daily contact with stainless steel anti-theft nets, stainless steel doors and windows, stainless steel screens, and stainless steel staircase handrails. Compared with other materials, stainless steel has the advantages of simplicity, grandeur, rust resistance, and durability, making it the darling of home decoration.

2. Public facilities

The demand for stainless steel decorative pipes in public facilities is also increasing. The demand for public facilities such as stainless steel fences, stainless steel guardrails, street lights, and cultural decorative landscapes is also rapidly increasing.

3. Mechanical structure

The demand for stainless steel decorative pipes in mechanical structures is very high. Stainless steel has excellent properties such as durability, rust resistance, corrosion resistance, and strong metal texture, which are just in line with the application of mechanical structures. In addition, in recent years, the demand for pipes used in automotive mechanical structures has increased rapidly, which has also led to a rapid increase in the demand for stainless steel pipes used in automotive mechanical structures.

4. Protective windows and doors

Nowadays, many protective windows and doors are made of stainless steel material, which not only has a long service life but also has high strength, making it very suitable for making protective windows and doors and windows for high-rise residential buildings.

439 Stainless Steel Coil
Type 439, a titanium-stabilized 18% chromium alloy, is a ferritic stainless steel designed to resist corrosion in a wide range of oxidizing environments from fresh water to boiling acids.Type 439 is also used in many oxidizing environments, where Type 304 is considered adequate for general corrosion resistance, but is subject to chloride stress corrosion cracking. This variation does not require post-weld annealing to restore ductility or provide resistance to intergranular corrosion.

Excellent resistance to stress corrosion cracking, good weldability, high thermal conductivity and low thermal expansion properties make Type 439 stainless steel ideal for many applications.

Application
Appliances
Hot water tanks, home furnaces
Automotive
Hard-to-form exhaust system components, tube manifolds, mufflers
Heat exchangers for power generation

pickled and oiled steel


Hot Rolled Pickled and Oiled Steel Coil / Sheet

Pickled and Oiled Sheet
Hot rolled pickled and oiled sheet is steel that has been pickled and oiled after hot rolling. The pickling process removes oxidized skin and rust from the steel surface, while the oiling process applies a protective layer of oil to prevent future rusting. The resulting steel is easier to process, offers many manufacturing advantages, and has a smoother surface finish than hot rolled steel that has not undergone this process.

What is hot rolled pickled and oiled steel?
Hot rolled pickled and oiled is steel that has had its oxide film removed and oiled to help resist corrosion. During the pickling process, the hot rolled pickled and oiled steel is descaled in a hydrochloric acid bath. The scale-free surface facilitates forming, bending, stamping and painting, saving production costs and improving the quality of finished parts. The pickling and oiling process produces durable hot rolled steel with improved formability, while providing a cleaner surface for painting with limited deterrent to rust. hunter steel supplies hot rolled pickled and oiled steel sheet and coil.
