                           MATERIAL SAFETY DATA SHEET



                    Confirms to Requirements of OSHA Standard 1910.1200



                               HAZARD COMMUNICAITON



I.     Product Identification:         Austenite Manganese Steel Castings Bearing Material

                                       Codes Containing the Letters G, L, or R.



II.    Hazardous Components:

Molybdenum              7439-98-7      0-2%           10.0                   15.0



III.   Overview:



       There are no chemical hazards from these castings in solid form at room temperature.

       Machining, grinding, welding and flame or Air-Arc cutting of castings can generate

       dust or fume. Most of this will be iron or iron oxide and overexposure to iron can

       cause siderosis or iron pigmentation of the lungs. Little or no disability results from

       siderosis.



IV.    Physical Data:



       Odorless silver gray solid with a S.G. of about 7.9. Other properties as BP, VP and

       water solubility are not applicable.



V.     Fire and Explosion Data:



       Austenitic Manganese Steel castings will not burn or explode.



VI.    Health Hazard Data:



       Eyes:            Metal particles in the eyes may cause irritation if not removed.

                        Particles should be removed by a trained person.



       Skin Contact: No hazards known.



       Breathing:       Prolonged or repeated exposure to iron oxide fume may cause

                        siderosis. Maintain adequate ventilation when welding on or thermally

                        cutting castings.

                                                                                            Page 2



        Ingestion:       Not Applicable





VII.    Reactive Data:



        Austenite Manganese steel castings are chemically stable. Hazardous polymerization

        will not occur.



VIII.   Spill and Leak Procedure:



        Dust collected from machining, welding or thermal cutting may be classified as

        "Hazardous Waste". Also, castings can be recycled. Consult local authorities about

        disposition of these items.



IX.     Protective Equipment:



        Respiratory:     Wear NIOSH approved respirator for dust or fume if concentrations

                         exceed the TLV or PEL.



        Ventilation:     Provide general ventilation and/or local exhaust if necessary to

                         maintain concentration below TLV.



        Eye Protection:         Safety glasses with side shields and/or face shields for

                                grinding; goggles or helmet for welding.



        Other:           Protective apron and gauntlets when welding on or thermally cutting

                         castings.



X.      Special Procedures:



        Storage requires no special requirements.
