What is the difference between ASTM A358 TP304 and 316L? (136)

Both are austenitic stainless steels, which means they have a higher chromium and nickel content than standard alloys. However, the difference between them is the amount of molybdenum that is present. ASTM A358 TP304 contains around 8% molybdenum whereas 316L has approximately 10-14%. This extra molybdenum increases the corrosion resistance of 316L to a greater degree than that of 304. As a result, 316L is typically used in environments where there may be more exposure to acidic chemicals or salty water.

Other differences include strength: 304 has a tensile strength range of 485-620MPa whereas 316L is 490-660MPa. Also, depending on their environment, 304 and 316L may differ in their heat treatment process. In certain situations such as cryogenic applications (where temperatures reach -200°C), TP304 should not be used but 316L can withstand these extreme conditions better.

What are classes of ASTM A358 316L? (177)

Class 1 includes the welded pipe with good mechanical properties, high ductility and good weldability. The composition is typically balanced to maximize corrosion resistance, durability, and strength. Class 1 also has very low carbon content and does not require heat treatment for it to achieve the desired properties.

Class 2 of ASTM A358 316L has similar mechanical and chemical properties as Class 1, however, its carbon content is higher than that of Class 1. This requires additional steps such as solution annealing after welding to minimize intergranular corrosion or cracking.

Class 3 requires additional testing and inspection during the manufacturing process to meet the stringent requirements for highly stressed applications, such as aerospace components or pressure vessels. It has higher alloy content compared to other classes of this grade, resulting in greater strength and durability but decreased ductility.

Finally, Class 4 has very low sulfur levels and ultra-low carbon content making it ideal for nuclear power plant applications which require the highest levels of purity and cleanliness due to increased safety concerns associated with nuclear power generation.

Which property of ASTM A358 TP304 make it suitable to use in high temperatures? (118)

This is an austenitic stainless steel with excellent high-temperature properties, making it suitable for use in elevated temperatures. It has a high melting point of 2,540 °F (1,390 °C) and good oxidation resistance of up to 870 °C in intermittent service. Additionally, the grade has good creep strength and is generally resistant to carburization, sulfur attack, and stress-corrosion cracking.

In comparison to other grades of stainless steel such as 304L or 321, TP304 offers improved tensile and yield strength even at elevated temperatures, providing added safety benefits when working with heated equipment. Ultimately, this makes TP304 ideal for a range of applications that require consistent exposure to heat including petrochemical facilities, exhaust systems and machinery components.

 

What is the cost of  ASTM A358 316L? (112)

The cost of this steel depends on several factors, including the size, shape and quantity required. Generally speaking, this type of steel is quite expensive compared to other stainless steel grades due to its corrosion-resistant properties. The cost can range from $2,000 – $5,000 per metric ton depending on market conditions and quality standards.

The price may also vary depending on the type of supplier you are using; smaller local suppliers may charge more than large-scale international suppliers. Additionally, different processes used to fabricate and form the metal can affect its overall cost. When shopping for this kind of steel, it is important to consider all costs associated with your purchase.

How can I import ASTM A358 TP304 cheaply in Qatar? (140)

The best way to import this grade of steel cheaply in Qatar is to research potential suppliers online. First, make a list of potential suppliers and then contact each one directly to inquire about their prices. It’s important to ask them for quotes in writing so you have evidence of their offer. Additionally, many suppliers are open to negotiating the price if you place a large enough order or can provide favourable payment terms.

Also, look into using a purchasing agent to get discounted prices by leveraging bulk-buying opportunities. When researching, take into consideration any shipping costs or customs duties that might be associated with importing materials into Qatar as this will affect your overall costs. Lastly, read customer reviews on different suppliers before making your decision to ensure that you’re getting a good quality product at the right price.
