Read this blog to find out more about the applications of 6% Moly, the origins of the material, and its many benefits and properties.

the applications of 6% Moly

As a global stockholder and supplier of high-performing pipes, fittings and flanges, Special Piping Materials (SPM) is a renowned expert in knowing the advantages and applications of different material grades.

From Stainless Steel to Duplex, Super Duplex and Nickel Alloy, the team at Special Piping Materials can always advise clients on what material will best suit their project. We have a wide range of specialist products available in each of these materials.

Special Piping Materials is also an expert in 6% Moly and we stock 6% products in each of our seven global warehouses. But what is 6% Moly and where did it originate from? What are the applications of 6% Moly? Read on to find out exactly what is 6% Moly, what advantages this material has and in what scenarios it can be used.

Overview of 6% Moly

So, what is 6% Moly? First of all, ‘Moly’ is an abbreviation of ‘Molybdenum’ while 6% Moly Alloy is a metal consisting of two or more metallic elements, where at least 6% of the metal content is molybdenum. Metal alloys are usually created to create a ‘hybrid’ material with enhanced properties such as greater strength or greater resistance to corrosion.

Molybdenum is silver in colour and is regularly chosen as an alloying metal due to its very high melting point. Interestingly, it is known to have the sixth-highest melting point of any element in the world and because of this, it is often used in applications where it is required to withstand extremely high heat. Subsequently, pure Molybdenum can be found in places like heating elements in furnaces, aircraft parts, filaments and even military armour electrical contacts.

It is a very useful metal and when it is used to produce an alloy, molybdenum can increase the strength, electrical conductivity and hardness of the metal it is combined with, as well as its resistance to wear and corrosion. This is why the applications of 6% Moly are so numerous.

6% Moly Alloys also contain high levels of chromium and nitrogen which add to their ability to withstand corrosion and stress cracking. They are part of the austenitic steel group which is the most commonly used grade of steel and is known for good formability.

Origins of 6% Moly

If we want to review the many applications of 6% Moly, it is useful to look at its origins.

According to the Royal Society of Chemistry, the new element Molybdenum was first announced in the autumn of 1781. It was originally discovered by a Swedish Chemist, Peter Jacob Hjelm, who named the metal after the Greek word ‘molybdos’ which means ‘lead’.

The group of 6% Moly alloys were first created in the early 1970s. This was due to a demand for a relatively cost-effective alloy with significant resistance to corrosive brackish water and seawater environments.

Understandably, the main industries that drove this need for a new alloy were the power generation and nuclear power industries. The other alternative metals in the market were thought to be too expensive or not resistant enough to corrosive environments.


Benefits of 6% Moly

6% Moly Alloys are purposely created for their variety of helpful properties. These properties mean that 6% Moly products, such as pipes, fittings and flanges, are in high demand in industrialised, engineering and manufacturing markets. The most noteworthy and helpful property of 6% Moly Alloy is its ability to withstand heat much more than steel and nickel-based superalloys. If we are likening it to other austenitic stainless steels, 6% Moly is also known to be much stronger.

6% Moly is known for these benefits and characteristics:

  •  – High density
  •  – Excellent impact toughness
  •  – High melting point
  •  – Very high resistance to chloride corrosion
  •  – Excellent thermal conductivity
  •  – Excellent electrical conductivity
  •  – Very high melting point
  •  – Excellent workability
  •  – Excellent weldability
  •  – Highly resistant to pitting, crevice and general corrosion

All of these benefits make this metal very popular and there are many known applications of 6% Moly. There are certain specialist mills around the world which are known for manufacturing this high-performing metal. Special Piping Materials works with several of these mills to ensure that the best products possible reach our clients.

The applications of 6% Moly

Alongside this long list of benefits, 6% Moly comes with an equally long list of applications. Understandably it is often used in corrosive and extremely hot environments but let’s take a look at these applications more closely.

Special Piping Materials deals with 6% Moly products daily, and we also have many 6% Moly products in stock in our warehouses. Here are just some of the applications of 6% Moly that we have supplied:

  •  – Seawater handling equipment such as heat exchangers and cooling water pipes
  •  – Tall oil distillation columns and equipment
  •  – Chemical process plants
  •  – Flue gas desulphurization scrubbers
  •  – Tanks and pipelines for various chemicals with high halide levels
  •  – Oil and gas production equipment
  •  – Sea and Brackish Water pipelines
  •  – Desalination Plants
  •  – Food processing equipment
  •  – Pulp Mill Bleach Systems
  •  – Subsea piping

6% Moly and Special Piping Materials

Special Piping Materials has developed relationships with some of the leading manufacturers of 6% Moly products across the world and we are proud of our strong supply chain.
