About Hot Rolled
Hot rolling is a metalworking process. Such as steel ingots or billets are difficult to deform and process at room temperature, they are generally heated to 1100 to 1250° for rolling, this rolling process is called hot rolling. Most steel materials are rolled by hot rolling, the steel delivered in the hot-rolled state has a certain degree of corrosion resistance due to the high temperature, so it can bestored in the open air. In addition, hot rolling is that it can destroy the casting structure of the ingot, refine the grain of the steel, eliminate structural defects, make the steel structure dense, and improve the hardness of the hot rolled steel.
304H Stainless Steel Composition
304h stainless steel is stainless steel that is ideal for foundries due to its unique set of chemical properties. This alloy combines iron, chromium, nickel, and other elements in its composition to create a robust and durable material that can last for many years in extreme heat or high-pressure situations. Not only does 304h stainless steel resist oxidation and corrosion but it also stands up well to abrasion, making it the perfect choice for many industrial applications. Additionally, 304h’s chemical composition creates a strong bond with other metals which helps ensure that welds remain extremely strong and intact over time. In summary, 304h stainless steel is an ideal solution for many industrial needs due to its balanced combination of beneficial properties.

304H Stainless Steel Properties
UNS S30409 is a high carbon austenitic stainless steel that is typically used in elevated temperature service. Some of the key properties of 304H stainless steel include the following:
- Good formability
- High strength
- Excellent weldability and traceability
- Good oxidation resistance in intermittent service up to 1500°F
- Good stress rupture and creep strength properties
- Higher carbon content for improved high-temperature strength
- Let’s take a more detailed look at some of these key properties.
Formability:
304H austenitic stainless steel can be easily formed using conventional methods. This high-strength material exhibits good ductility in the annealed condition.
High Strength: In the as-welded condition, 304H stainless steel offers higher strengths than standard 304 austenitic stainless steel. This higher strength level is due to the higher carbon content of 304H stainless steel.
Weldability and Brazeability:
Like other austenitic grades, S30409 has excellent weldability and traceability. These properties are due to the presence of austenite in the microstructure of 304H stainless steel.
Oxidation Resistance: The higher carbon content of 304H stainless steel gives this grade improved high-temperature strength compared to standard 304 austenitic stainless steels. As a result, 304H stainless steel is often used in applications where exposure to elevated temperatures is a concern.
Stress Rupture and Creep Strength Properties: The higher carbon content of 304H also gives this grade improved stress to rupture and creep strength properties compared to standard 304 austenitic stainless sheets of steel. These properties make 304H an ideal choice for high-temperature applications such as boiler tubes and piping systems.
304H Stainless steel Uses
304h stainless steel is often used in applications that require superior strength and resistance to corrosion. It is the alloy of choice for chemical processing, petrochemicals, and other industrial processes, as it offers increased strength for such environments. It also has a high resistance to sulfide stress cracking caused by sulfur compounds and good pitting resistance in nearly every chloride environment, making it an excellent choice for piping systems exposed to sea or brackish waters. Its versatility lends it to other uses like refinery heat exchangers, pulp machines, synthetic fiber-producing equipment, pipelines, cladding on steel structures, and food processing equipment, just to name a few.
