Generally, the two most commonly selected materials for heat exchanger are aluminum and copper. Both metals have the optimum thermal properties and corrosion resistance to make them ideal choices

Cast Iron

Nickle is a major alloying element in SS904L with a proportion of 25%.  Application of SS904L are as below: Oil refinery components. Pulp and paper processing industries. Gas scrubbing plants. Wiring in electrostatic precipitators. Acetic, phosphoric, and sulphuric acid processing…   Read more»

Molybdenum adds corrosion resistance and high-temperature strength as well as durability. 
This element increases elevated temperature strength through solid solution hardening. and molybdenum is ferrite former, That means that this improves the corrosion resistance of an austenitic stainless steel.

In grade 304 stainless, the maximum carbon content is set at 0.08%, whereas grade 304L stainless steel has a maximum carbon content of 0.03%. The “L” in 304L can be interpreted as meaning extra-low carbon.

The passive layer forms because of the chromium added to stainless steel. Stainless steel must have at least 10.5% chromium in order for the passive layer to form. The more chromium that is added, the more stable the passive layer…   Read more»

Tool steel is a type of carbon alloy steel that is well-matched for tool manufacturing, such as hand tools or machine dies. Its hardness, resistance to abrasion, and ability to retain shape at increased temperatures are the key properties of…   Read more»
