Standards monitoring is a free service designed for you who wish to be alerted of changes to or new editions of the standards required in your work.

ASTM A941:13a

Webprint Printed and bound. Carbon is always present in stainless steel. Heat treating by heating to a high temperature, quenching and then tempering develops the martensitic phase. This service is not available if you are a URL user where you do not log in with s941 email address.

Niobium additions prevents inter-granular corrosion, particularly in the heat effected zone after welding. The addition of nitrogen helps to raise the yield strength levels back to the same level as standard atm.

Nickel is the essential allying element in the series stainless steel grades. Read more about subscriptions. The addition of molybdenum to the Cr-Fe-Ni matrix adds resistance to localized pitting attack and better resistance to crevice x941 particularly in Cr-Fe ferritic grades. MANGANESE Generally manganese is added to stainless steels to assist in de-oxidation, during melting, and to prevent the formation of iron sulfide inclusions which can cause hot cracking problems.

NOK 1 ,00 excl. Once the composition contains at least The most common grade today is with 0. You need to log in before adding standards to the monitoring service. There are over different stainless steels with unique alloying element combinations.

The moment new editions of the standards you monitor are released, changes are made, or appendixes are published, you will be alerted by email.

Alloying elements are added to change their properties. Monitoring Standards monitoring is a free service designed for you who wish to be alerted of changes to or new editions of the standards required in your work.

ASTM A – Terminology Relating to Steel, Stainless Steel, Related Alloys, and Ferroalloys

Subscription – always available and updated A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition. In all categories except martensitic, the level is kept quite low.

Carbon can have an effect on the corrosion resistance. Generally manganese is added to stainless steels to assist in de-oxidation, during melting, and to prevent the formation of iron sulfide inclusions which can cause hot cracking problems. If, in localized areas, the chrome is reduced to below The amount of carbon is the key. The benefits of a subscription: If you need to be able to add standards to the monitoring service, you must register as a user with your own username and password.

The addition of sulfur, however, does reduce the resistance to pitting corrosion. The higher the chromium level the greater the protection. Today all 9a41 steel are finished in an AOD vessel and the carbons levels are generally low due to the absence of oxygen.

A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition. Small amounts of silicon and copper are usually added to the austenitic stainless steels asttm molybdenum to improve corrosion resistance to sulfuric acid.

It also makes the material non-magnetic.

In martensitic grade the level is deliberately increased to obtain high strength and hardness. The low carbon levels, however, tend to reduce the yield strength. Start Webshop Product catalog Product presentation. These alloying additions improved corrosion resistance in different service environments and determine strength levels, formability, machinability and other desirable characteristics.

When stainless steel is melted in air, it is difficult to reducing the carbon levels.

Niobium helps prevent the formation of chrome carbides, that can rob the microstructure of the required amount of chromium for passivation. At this high level, something was needed to stabilize the carbon and titanium was the most common way. Titanium is the main element used to stabilize stainless steel before the use of AOD Argon-Oxygen Decarburization vessels.

Metals are rarely used in their pure form. Sulfur is generally kept to low levels as it aatm form sulfide inclusions. This ensures that you are always up-to-date and saves you both time and money.
