Why You Should Use 316 Stainless Steel Rods

 The difference between 304 and 316 stainless steel is very commonly misunderstood, or not known at all, and can have a huge impact on the reliability of survey results, and what you’re achieving for your clients. Let’s explore this further.

304 stainless steel contains a mix of chromium and nickel and is slightly responsive to magnetic fields. The addition of the nickel (8-10.5%) modifies the physical structure of the steel and then, theoretically, makes it non-magnetic. However, through extended periods of continuous motion in one direction, and the resulting friction, grade 304 stainless steel can become slightly more magnetic.

Additionally, if the steel alloy is mechanically deformed during the manufacturing process the internal structure of the steel may change causing the rods to be partly magnetic from the moment they leave your supplier’s warehouse. They haven’t even seen pay dirt yet.

On the other hand, 316 type stainless steel is a molybdenum-alloyed steel and contains a higher concentration of nickel than 304 does, approximately 10-14%. The result is the 316 type is negligibly responsive to magnetic fields, making it perfect for applications where non-magnetic metal is required.

Why You Should Use 316 Stainless Steel Rods

Thanks to the higher concentration of nickel in 316 type drill rods, these are significantly more resistant to becoming magnetised by continuous friction and therefore less likely to negatively impact your client’s data.

Corrosion Resistance Of 2205 Duplex Steel pipe

  2205 duplex stainless steel is a cost effective solution for many applications where the 300 series stainless steels are susceptible to chloride stress corrosion cracking. Stress corrosion cracking occurs when stainless steels are subjected to tensile stress, while in contact with solutions containing chlorides. Increasing temperatures also increase the susceptibility of stainless steels to stress corrosion cracking.We have wide range of sizes in our stock of  2205 Duplex Stainless Steel Pipe  & 2507 Super Duplex Stainless Steel tube,S31803 Welded Pipes Tubes . 2205 steel has excellent corrosion resistance and is superior to grade 316, performing well in most environments where standard austenitic grades may fail. 2205’s low carbon content gives the grade a high resistance to intergranular corrosion and has better resistance to uniform, pitting and crevice corrosion due to its high chromium and molybdenum content.  As 2205 is a duplex stainless steel, the grade is also less sensi

what is the forged shaft manufacturing process

图片
 Like casting processes, forging has also been used since the beginning of civilization to produce metallic goods. In its present form, forging is defined as the process in which metals are shaped using compressive forces.  The general steps of an open die forging process can be enumerated as follows: Rounding of Stock Primarily the heated metal is fixed to an anvil and compressed with lateral and/or vertical dies to form a cylindrical shape. This step is important because it grants structural stability and improves the physical strength of shaft forgings . Setting Dimensional Standards Simultaneous action of multiple dies results in the shaping of a cylindrical metal rod to the desired length, thickness, and shape. Appropriately sized dies are used to deform the bar along its length and provide it the thickness expected of the final shaft forgings .  Consequently, edging and fullering processes are conducted onto the stock. Here, the ends of the material are concentrated using a conca

The Material Of Duplex UNS S31803/ S32205

图片
  Duplex UNS S31803/ S32205   are the most common duplex grades in the market. They have very good resistance to localized corrosion and stress corrosion cracking in combination with high mechanical strength. UNS numbers S31803 and S32205 represent alloys with more characteristics in common than distinct differences. Firstly, they are both stainless steels with similar elemental compositions. Both S31803 and S32205 belong to the duplex 2205 family, which means they comprise almost equal parts austenite and ferrite. Secondly, they are both extremely strong and durable alloys.They are widely used in oil & gas, hydro power, pressure vessels, pulp & paper, structural components and chemical tankers. The alloys are not intended to be used at temperatures above 300°C due to embrittlement. APPLICATIONS The main applications are for details with special requirements for high corrosion resistance. S31803/ S32205 are characterized by: • High resistance to stress corrosion cracking in hal
